I'm using Firefox Nightly of 46.0a1 version (there is only 42v. for OS X, and Push API requires 43v).
And I'm getting this error:
DOMException [AbortError: "Error retrieving push subscription"
code: 20
nsresult: 0x80530014]
Here is snippet where this error in thrown:
navigator.serviceWorker.ready.then(function (serviceWorkerRegistration) {
serviceWorkerRegistration.pushManager.subscribe()
.then(function (subscription) {
endpoint = subscription.endpoint;
console.log('subscription endpoint: ', subscription.endpoint);
subscribeOnServer();
})
.catch(function (e) {
// here that error is raised
errorNotification.innerHTML = 'Unable to subscribe to push';
}
});
});
In Chrome this place doesn't throw anything and I get subscription with a properly endpoint.
I have recently found that this error may rise if your browser is behind a proxy which does not support web sockets (push service uses web sockets internally).
It doesn't throw for me.
There was a syntax error in your snippet, but I guess that wasn't the issue (otherwise it would have failed in Chrome as well).
Here's the snippet I've used:
navigator.serviceWorker.ready
.then(function(serviceWorkerRegistration) {
console.log('asd');
serviceWorkerRegistration.pushManager.subscribe()
.then(function(subscription) {
endpoint = subscription.endpoint;
console.log('subscription endpoint: ', subscription.endpoint);
})
.catch(function(e) {
console.log(e);
});
});
I got this error when my service-worker had errors(tried to access non existant store in indexedDb) and so even though it installed but push notifications were not getting subscribed with above error.

I created a Firebase App using NodeJS/VueJS and trying to setup Cloud Messaging.
I created a firebase-messaging-sw.js file, and added messaging on my main.js.
On my app I included firebase and on my mounted I did this (as stated on the doc) :
const messaging = firebase.messaging();
messaging.getToken({ vapidKey: "<KEY>" })
.then((currentToken) => {
if (currentToken) {
console.log('client token', currentToken)
} else {
console.log('No registration token available. Request permission to generate one.');
}
}).catch((err) => {
console.log('An error occurred while retrieving token. ', err);
});
Then I am going to my webapp and I have the following error :
"Uncaught TypeError : cannot read property of undefined (reading 'addEventListener')"
This error kinda lost me since I don't know where does it come from.
When looking on the error I saw that :
Looking into the source register.ts it redirects me to this :
navigator.serviceWorker.addEventListener('message', e =>
messageEventListener(messaging as MessagingService, e));
But I don't understand the problem, I tried to describe as much as possible all the steps that leaded to the error. Even when I comment the code of my mounted I still have the error
Thanks in advance,
I have a node API that is working fine when tested using postman.
But when I use this API in my angular project there occurs an error and browser don't get any response there it keep waiting for a response. When I go to console I see the error message.
How I can make that error message to be sent back to the browser with full stack trace
In general, you will need to catch that error, then populate http response object with it just the same as if you were sending successful response data back to the requestor.
Synchronous processing:
try {
// do my requested stuff
res.status(200).json({something:"returned"});
} catch(ex) {
res.status(500).json(ex);
};
Promises:
Promise.resolve()
.then(() => {
// do my requested stuff
// return my results stuff to the client
res.status(200).json({something:"returned"});
})
.catch((ex) => {
// return 500 error and exception data to the client
res.status(500).json(ex);
});
Also, as standard practice you should catch all errors, and at the very least, you should return a 500 to the browser res.status(500) so you don't leave it hanging when unexpected issues arise.
And, of course you can return html rather than json, and/or more info in the response.
Good luck.
I keep getting the following error response from node when trying to run a read call to rally:
Error: getaddrinfo ENOTFOUND rally1.rallydev.com rally1.rallydev.com:443
I am using the Rally Node SDK, and node v7. I am on a local machine. It is successfully reaching and logging the 'releaseoid' before the 'try'.
I feel like I am not specifying http (which I was before and now completely commented out the server, letting the SDK default it). But it is continuing to give back that error. I could not find (or possibly understand) other general Node guidance that may address this situation. I am not clear where port 443 is coming from as I am not specifying it. Is the SDK adding it?
If I specify the server address without http:
server: 'rally1.rallydev.com',
I still get an error, but this time:
Error: Invalid URI "rally1.rallydev.com/slm/webservice/v2.0null
I am new to Node and not sure if I am having a problem with Node or the Rally Node SDK.
Code below.
var rally = require('rally');
var rallyApi = rally({
apiKey: 'xx',
apiVersion: 'v2.0',
//server: 'rally1.rallydev.com',
requestOptions: {
headers: {
'X-RallyIntegrationName' : 'Gather release information after webhook',
'X-RallyIntegrationVendor' : 'XX',
'X-RallyIntegrationVersion' : '0.9'
}
}
});
// exports.getReleaseDetails = function(releaseoid, result) {
// console.log('get release details being successfully called');
//
//
//
// }
module.exports = {
getReleaseDetails: async(releaseoid) => {
console.log(releaseoid);
try {
let res = await
rallyApi.get({
ref: 'release/' + releaseoid,
fetch: [
'Name',
'Notes',
'Release Date'
]
//requestOptions: {}
});
res = await res;
console.log(res);
} catch(e) {
console.error('something went wrong');
console.log(e);
}
}
}
That mostly looks right. I haven't tried to use async/await with the node toolkit yet- it would be interesting to see if that works. It should, since get and all the other methods return promises in addition to handling standard node callback syntax.
But anyway, I think the issue you're having is a missing leading / on your ref.
rallyApi.get({
ref: '/release/' + releaseOid
});
Give that a shot?
As for the network errors, is it possible that you're behind a proxy on your network? You're right though, https://rally1.rallydev.com is the default server so you shouldn't have to specify it. FYI, 443 is just the default port for https traffic.
Apologize for my English.
I have a node js script that has to send AMQP messages to device using IoT hub. I've took thiss script from github of azure iot. Here is this sample.
Here is this sample
Here is my script, based on this one:
console.log("creating the client");
var Client = require('azure-iothub').Client;
console.log("client has been created");
var Message = require('azure-iot-common').Message;
console.log("message has been created");
var connectionString = "HostName=id**.azure-devices.net;SharedAccessKeyName=iothubowner;SharedAccessKey=***;
console.log(connectionString);
var targetDevice = 'devicesergey';
var client = Client.fromConnectionString(connectionString);
client.open(function (err) {
if (err) {
console.error('Could not connect: ' + err.message);
}
else {
console.log('Client connected');
var data = JSON.stringify({ text : 'foo' });
var message = new Message(data);
console.log("json message is created")
console.log('Sending message: ' + message.getData());
client.send(targetDevice, message, printResultFor('send'));
console.log("message has been sent");
}
});
function printResultFor(op) {
return function printResult(err, res) {
if (err) {
console.log(op + ' error: ' + err.toString());
} else {
console.log(op + ' status: ' + res.constructor.name);
}
};
}
That works fine locally and I see messages on my device emulator. But when I try to put it to Azure Mobile Services API and try to run it, I see this message on logs:
An unhandled exception occurred. Error: One of your scripts caused the service to become unresponsive and the service was restarted. This is commonly caused by a script executing an infinite loop or a long, blocking operation. The service was restarted after the script continuously executed for longer than 5000 milliseconds. at process.Server._registerUncaughtExceptionListenerAndCreateHttpServer._onUncaughtException (D:\home\site\wwwroot\node_modules\azure-mobile-services\runtime\server.js:218:17) at process.EventEmitter.emit (events.js:126:20)
And sometimes I see this IIS error
I know exactly that this line occurs this function: client.open(function....
I've evem tried to leave only client.open() and send a messages out of this function. But in this case I see "client is not connected".
I asked about this stuff on github. They advised me to asked here. Maybe someone know how to solve this issue (with script or Azure). I would be very very greatfull!
Thank you!
The Mobile Service Custom API is a script that expose the functionality of the express.js library, please see the section Overview of custom APIs of the offical document "Work with a JavaScript backend mobile service"
I reproduced the issue successfully. I guess your script was not wrapped in the code below as the body block, and not sent the response to the client like browser.
exports.get = function(request, response) {
// The body block
....
response.send(200, "<response-body>");
}
For more details of Mobile Service Custom API, please see https://msdn.microsoft.com/library/azure/dn280974.aspx.
Update:
I changed your code as below.
And In order to facilitate the test, I changed the permission for the api as below, then I can access the api link https://<mobile-service-name>.azure-mobile.net/api/test with browser.
I've just tried to execute my script on new Azure MS and it was unsuccesfully.
I will write my step-by-step actions, maybe you can see anything wrong, because I'm not so good in NodeJS.
Add a new Azure MS with new SQL Database
Add a new API "dev". Access - everyone for all points. Here is source code:
exports.get = function(request, response) {
console.log("creating the client");
var Client = require('azure-iothub').Client;
console.log("client has been created");
var Message = require('azure-iot-common').Message;
console.log("message has been created");
var connectionString = "HostName=i***.azure-devices.net;SharedAccessKeyName=iothubowner;SharedAccessKey***";
console.log(connectionString);
var targetDevice = 'devicesergey';
var client = Client.fromConnectionString(connectionString);
client.open(function (err) {
if (err) {
console.error('Could not connect: ' + err.message);
}
else {
console.log('Client connected');
var data = JSON.stringify({ text : 'foo' });
var message = new Message(data);
console.log("json message is created")
console.log('Sending message: ' + message.getData());
client.send(targetDevice, message, printResultFor('send'));
console.log("message has been sent"); }
});
response(200, "Hello, world!");
};
function printResultFor(op) {
return function printResult(err, res) {
if (err) {
console.log(op + ' error: ' + err.toString());
} else {
console.log(op + ' status: ' + res.constructor.name);
}
};
}
If I try to execute this stuff it occurs "no azure-iothub" and "no azure-iot-common", so I need to use git to add these npm.
I clone this repository to my local dir using git access to Azure MS https://id.scm.azure-mobile.net/id.git
Enter the "API" folder and add the NPMs:
Then I perfom "Rescan", "Save changes", "Commit", "Push" on
After these actions I execute my script by path "http://id**.mobile-services.net/api/dev" and don't see anything o see the error "500.1013" and these messages on logs (id depends):
An unhandled exception occurred. Error: One of your scripts caused the
service to become unresponsive and the service was restarted. This is
commonly caused by a script executing an infinite loop or a long,
blocking operation. The service was restarted after the script
continuously executed for longer than 5000 milliseconds. at

I can't realize what I'm doing wrong
UPDATE:
I've tried to use Kudu console for installing the npms and it returns many errors. If i figured out correctly, I need to update my node js and npm. But I don't know how to do this and I didn't manage to find a solution.
Here are logs:
I have lack of reputation, so I am not allowed to past log scripts.
I've tried to do these actions, but it doesn't help:
at the root of the repo, you'll find a .deployment file that has:
command = ..\ZumoDeploy.cmd Change it to
command = deploy.cmd And create a deploy.cmd next to it containing:
set
NPM_JS_PATH=%ProgramFiles(x86)%\npm\1.4.9\node_modules\npm\bin\npm-cli.js ..\ZumoDeploy.cmd Commit both files and push.
I'm confused. How is it possible? Azure Mobile services don't permit to install azure-iot-hub npm). What can I do with this issue?
UPDATE2:
Peter Pan - MSFT, you advised me to use Kudu DebucConsole to install necessary npm. But when I try to do it - I see errors.
I've messaged about this issue to "npm" command on github, they say that the version of npm which Azure is used to - is completely unsupported.
htt ps://github.com/npm/npm/issues/12210#event-615573997
UPDATE3 (04/12/2016)
I've solved this issue by different way. Created my own node JS script that is listening a port, read GET params(deviceId and message) and send D2C messages.
Unfortunately, I still can't get trow the Azure issue.
UPDATE4
Peter Pan gave me an advise how to use another version of nodejs and npm. Now I've succesfully installed necessary NPM modules. But now Azure Mobile Script APIs don't work, it shows me {"code":404,"error":"Error: Not Found"} on any script that I try to get in my browser.
Maybe I've deleted something when I tried to do these stuffs.
I am having a problem serving up error messages using express-mongoose-restify.
My schema has a hook like
myschema.pre('save', function(next){
// If validation fails
next(new Error('failed to validate model'))
})
For error handling I have (something similar to) the following code
resify.serve(express.Router(), mongoose.model('myschema', {
onError: function(err, req,res,next){
console.log(err)
res.status(400).json(err)
}
})
The output to the console when validation fails is as follows:
{ [Error: failed to validate model] statusCode : 400 }
In my client I have the following (jquery) ajax error handler:
$( document ).ajaxError(function( event, jqxhr, settings, thrownError ) {
console.log(jqxhr)
console.log(thrownError)
});
thrownErorr is equal to "Bad Request" and jqxhr has reseponseText: "{"statusCode" : 400}" similar (but parsed to JS) for the responseJSON. The message failed to validate model is not being sent to the client. I think that I am misunderstanding the type of object that err is in my sever side error handler. Any thoughts? Thanks in advance!
This is one of those cases where writing the question made me think of the right question to ask myself in order to answer it.
The V8 error object that is use by node does not send the additional information such as the stack, message etc when converted to JSON. My problem was solved by reading up on the properties of the Error object here.
In particular using the following handler, the error is successfully relayed to the client
onError : function(err, req, res, next){
res.status(400).json({
message : err.message,
stack : err.stack
})
}
