I'm working on a project which uses Npm request package for making request to an API server. On getting response, the callback processes the returned response. During this response processing I get the error: Failed to receive keepalive! Exiting. The following code will help you understand.
request({url: 'http://api-link-from-where-data-is-to-be-fetched'
},
function (err,res,body) {
//The code for processing response
}
Anybody can help me please who knows how to resolve this issue?
This might help answer this for you:
https://github.com/meteor/meteor/issues/1302
The last post on that page says:
Note that this is just a behavior of the develop-mode meteor run (and any hosting environment that chooses to turn on the keepalive option, which probably isn't most of them), not a production issue. And in any case, if your Node process is churning CPU for seconds, it's not going to be able to respond to any network traffic.
this post might help you : Meteor error message: "Failed to receive keepalive! Exiting."
Removing autopublish with meteor remove autopublish and then writing my own publish and subscribe functions fixed the problem.

I am using a Nodejs client to integrate with Google Smart Home.
When I request to RequestSync API, it sometimes shows the following error.
Error: Internal error encountered.
Although I saw the above error, it seems that the SYNC request has been triggered properly.
Does anyone know why this happens?
Since the request failed and returned an error, our app retries the RequestSync again and again, so I'd like to fix the error if possible.
Thank you.

I have reviewed tons of information in Google, but didn't found an answer.
More details, that can helps you to answer.
It happens suddenly. It worked OK, but about 1 week ago I start to get this error and cannot fix it. So I didn't change anything, just run add-on again, as I did it every day.
If I try to upload add-on manually I got error in terminal

The most possible reason (that I've found in google) is that I have wrong server time. But the time on my local machine is correct (at least for my timezone).
Anyone has any thoughts about this problem?
Thanks!
I kept randomly having this happen to me. It would be working, then run npm start and I would get the error. Since I'm not using a database right now, I simply removed all references to the juggling-sqlite database. This was in package.json, package-lock.json, config.json, and I just removed store.db. That got it working for me. Pretty frustrating that this happens, not sure a better way around it.
I am getting random restarts on a PM2 managed nodejs cluster. The only symptom I get on the error log is of the following pattern - an ENOTFOUND on dns.js.
Error: getaddrinfo ENOTFOUND walkinto.inhttp walkinto.inhttp:80
at errnoException (dns.js:28:10)
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:76:26)
Clearly the problem is a malformed server name - walkinto.inhttp is incorrect and it should be walkinto.in . The challenge is that this is not a host name hard coded in the code. There are many places in this fairly large code base that makes name resolution and it is of dynamic nature.
I have spent considerable time to pinpoint the root cause but so far have had no luck. I need help to print more log information from dns.js; probably a call stack 'may' would help to move forward.
Q1 : How to enable more detailed logging on nodejs core modules?
Q2 : What could cause a nodejs restart to happen for an ENOTFOUND? How to avoid a restart - This path is not desirable.
Q3: Are there any other smarter way to trouble shoot this problem?
Since there's no way for us to help you solve the issue without some code to go on, I'll answer your questions:
How to enable more detailed logging on nodejs core modules?
Run node with the inspect option and attach to the debugger with Chrome DevTools or another application. See these links:
https://nodejs.org/api/debugger.html
https://nodejs.org/en/docs/guides/debugging-getting-started/
What could cause a nodejs restart to happen for an ENOTFOUND? How to avoid a restart - This path is not desirable.
The Node runtime isn't restarting. The error you're seeing is generated from something similar to throw new Error(`getaddrinfo ${err}`), and any uncaught error from throw will crash the runtime.
The restart is happening because you run the app via PM2, and can be disabled by passing the --no-autorestart option to PM2. If you want to avoid the application from crashing, you should wrap whatever code that this could be generated from in a try/catch-block, and try to recover from the error.
Are there any other smarter way to trouble shoot this problem?
This is most likely not an issue with the dns stdlib module. If I understand correctly, you are performing name resolutions on dynamically generated data, and that is most likely your issue. Somewhere in the code you have one or more functions that are either not validating the generated data or are generating invalid data due to a bug. We can't help you solve that unfortunately, since you haven't provided any code to go on. Would be great if you could try to pinpoint what code might cause this and update the question with it.
I was getting this error in my request that was something like this:
var optionsSearch = {
host: 'https://mysite.sharepoint.com',
path: '_api/search/query?querytext="sharepoint"',
method: 'GET'
};
All did was removing the https:// leaving only mysite.sharepoint.com and it was fixed.
I'm following the guide at https://learn.microsoft.com/en-us/azure/app-service-mobile/app-service-mobile-xamarin-android-get-started-push (as well as the original Xamarin one that this appears to have cribbed from), but I'm running into a problem registering my client.
I am successfully logging a user in prior to setting up the push notification service.
Both GcmClient.CheckDevice(...) and GcmClient.CheckManifest(...) succeed, and my PushHandlerService is being called.
Push.RegisterAsync(...) in my PushHandlerService is throwing a MobileServiceInvalidOperationException because it received an HTTP 500 Internal Server Error from the service.
Looking at FREB logs, it appears that the "error" is actually supposed to be a success, and interestingly is somehow related to the EasyAuthModule:
NOTIFY_MODULE_COMPLETION ModuleName="EasyAuthModule_64bit", Notification="AUTHENTICATE_REQUEST", fIsPostNotificationEvent="true", CompletionBytes="297", ErrorCode="The operation completed successfully.
(0x0)" 05:51:01.092
Module_set_response_error_status
Warning ModuleName="EasyAuthModule_64bit", Notification="AUTHENTICATE_REQUEST", HttpStatus="500", HttpReason="Internal Server Error", HttpSubStatus="79", ErrorCode="Unspecified error
(0x80004005)", ConfigExceptionInfo="" 05:51:01.092

I take it the error is happening when you call client.GetPush().RegisterAsync()? This is currently an issue and we are deploying a fix on the Azure side to fix this. In the interim, you can see the fix for this here: https://adrianhall.github.io/develop-mobile-apps-with-csharp-and-azure/chapter5/android/
I have set a node server with Express middleware. I get the ECONNABORTED error randomly on some files when loading an HTML file which triggers about 10 other loads (js, css, etc.). The exact error is:
{ [Error: Request aborted] code: 'ECONNABORTED' }
Generated by this simplified code (after I tried to debug the issue):
res.sendFile(res.locals.physicalUrl,function (err) {
if (err)
console.log(err);
...
}
Many posts talk about this error resulting from not specifying the full path name. That is not the situation here. I do specify the full path and indeed the error is randomly generated. There are times when the page and all its subsequent links load perfectly and there are times when they do not. I tried to flush the cache and did not find any pattern to connect it with this.
This specific error appears to be a a generic term for socket connection getting aborted and is discussed in the context of other applications like FTP.
Having realized that the node worker threads can be increased, I tried to do so using:
process.env.UV_THREADPOOL_SIZE = 20;
However, my understanding is that even absent this, at most the file transfer may have to wait for a worker thread to be free and not get aborted. I am not talking about big files here, all files are less than 1 MB.
I have a gut feeling that this has nothing to do with node directly.
Please point to any other possibilities (node or otherwise) to handle this error. Also, any other indirect solutions? Retrying a few times could be one but that would be clumsy. EDIT: No, I cannot retry. Headers are already sent with the error!
A SIDE NOTE:
Many examples on the use of sendFile skip using the callback thereby giving the impression that it is a synchronous call. It is not. Do use the callback at all times, check for success and only then move on to the "next" middleware or take appropriate steps if the send fails for whatever reason. Not doing so can make it difficult to debug the consequences in an asynchronous environment.
See https://stackoverflow.com/a/36949631/2798152
Could it be possible that in some cases you terminate the connection by calling res.end before the asynchronous call to res.sendFile ends?
If that's not the case - can you pastebin more of your application code?
Uninstalling and Re-installing MongoDB solved this for me.
I was facing the same problem. It started happening when I had to force restart my laptop because it became unresponsive. On restarting, trying to connect to mongo server using nodejs, always threw ECONNABORTED error
