I am deploying a meteor application to a digital ocean droplet with meteor upload. Everything goes well, the application gets deployed, database works, seeding of data works etc. But there is one problem i can't seem to be able to solve.
I use the meteor-uploads package (https://github.com/tomitrescak/meteor-uploads) for file uploads. Locally everything goes well, the file gets uploaded, finished callback gets called etc. But once I have deployed the application to the server it keeps giving me on of these errors, :
POST http://*ip*/upload net::ERR_CONNECTION_REFUSED
POST http://*ip*/upload net::ERR_EMPTY_RESPONSE
POST http://*ip*/upload net::ERR_CONNECTION_RESET
Any ideas are welcome, I have searched all over for a solution but none seems to fit my problem. I also installed to a fresh droplet but that didn't help. In none of my browsers (Mac Chrome, safari & firefox) does it work, on my phone (Android 5.0) I get the same errors. I am using the newest Meteor version 1.1.0.1
On local host you don't need to set the environmental variables, but the host services provides you should.
Check this tutorial to see how to put the environment variables.
Because the file-upload needs a startup-server-configuration, like this.
//file:/server/init.js
Meteor.startup(function () {
UploadServer.init({
tmpDir: process.env.PWD + '/.uploads/tmp',
uploadDir: process.env.PWD + '/.uploads/',
checkCreateDirectories: true //create the directories for you
})
});
But im not sure if putting this on a startup will work on digital ocean, like i say you you enter it, run printing and check if the /.uploads/ exists

We have an install of Node.js running on a Windows Server 2012R2 web server. A developer created an application for us using Next/React/Node (I'm not a web developer so I'm unsure of the specifics of the various development tools used). This app works fine when manually started on the command line like this:
C:\NodeApps\pacifield>"C:\PROGRAM FILES\NODEJS\NODE.EXE" C:\NodeApps\pacifield\node_modules\next\dist\bin\next start
However this requires someone to manually login and restart the app whenever the server is rebooted or the app stops for whatever reason. I am trying to setup PM2 to run the app. I have it up and running fine until you browse to the app - at which point you get the following error:
next-server.ts:306 Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
See https://reactjs.org/link/invalid-hook-call for tips about how to debug and fix this problem.

I have checked and there is only the one installation of React in C:\NodeApps\pacifield\node_modules\react and the other suggestions don't seem to make sense when it runs fine outside of PM2. I have checked with ProcessExplorer that all the environment variables are the same (except for the additional ones PM2 adds) when the app is run from the command line vs. PM2.
Anyone have any suggestions?

I have been searching for why this has been happening, but recently I reinstalled Ubuntu 16.04 and I copied a Node + Express project to a flash drive then pasted it to the exact same corresponding location (~/Programming/project/). Upon doing that, everything else works as I would expect but Mongo is not responding when I make requests to it through Mongoose. I do not have any reason to believe that Mongoose is the reason for the failure to respond. I have a couple of routes in which I know should work, the exact same code works on my friend's machine (same Ubuntu, version and everything). I have uninstalled and reinstalled everything (Including Ubuntu) multiple times. The only thing that works is making a call to find something with a specific ID will return if and only if the ID does not exist. Mongo won't return all the records or anything else. The website just spins endlessly (locally hosted on my machine). However, using Mongo in the terminal works fine. I can query and get results as if everything is normal. Has this happened to anyone else or is there any ideas? I can try to include some code.
This does not work
Greeting.find({}, function(err, greetings) {
res.status(200).json(greetings);
});
This does work.
Greeting.findById(req.params.id, function(err, greeting) {
if(err)
res.status(404).json({"error": "Greeting with that ID does not exist"});
res.status(200).json(greeting);
});
EDIT:
Sorry, I am new to stack overflow so I am still getting the hang of what should be added or not...
mongoose.connect(database.url);
mongoose.connection.on('error', function() {
console.info("Could not run mongodb, did you forget to run mongod?");
});
The database.url is what it needs to be, the connection is open as far as I can tell...
I should also mention that while installing Ubuntu, I wiped my previous dual boot in favor of just having Ubuntu, and so I opted in for the hard-drive encryption... Could that be preventing Mongo from working properly? If so, how would I fix that?
The issue was in fact the encrypted hard drive. I reinstalled Ubuntu and that fixed it. I'm still not sure how to make it work with an encrypted disk.
I have recently started working with MongoDB and had it working for a small web test with node JS However. I new my implementation wasn't following a decent MVC structure. I began searching and found this website and read through it. It's implementation look good as well as following a good MVS skeleton structure.
Express/NodeJS/MongoDB CRUD Skeleton
I got to the part where he says 'HOORAY! We've got a functioning web server that is talking to Mongo. Part 1 is accomplished." Unfortunately, I went the local host specified and it says the 'site cannot be reached'. I am still fairly new to NodeJs, Mongo and Express and cannot figure out why it is not working.
I am not sure if I have done a step wrong time and time again which I doubt or if there something is missing that is stopping me from having it working.
The part before it says:
Awesome. Now to test it's all working in the terminal type npm start and you shouldn't see any errors:
kcoleman-mbp:nodewebapp kcoleman$ npm start
> nodewebapp#0.0.1 start /Users/kcoleman/Documents/projects/nodewebapp
> node ./bin/www
That part I get the same outcome with:
nodewebApp and node./bin/www
The page says to navigate to 127.0.0.0:3000, but the localhost usualy defaults to 127.0.0.1. I didn't see any code in the page where he defines the port to 127.0.0.0.
So try connecting to 127.0.0.1:3000.
Coming to nodewebApp and node./bin/www, it could be because the command might be present in pacakge.json. If you delete the nodewebApp from package.json, you won't be seeing the same in the command.
Versions
I'm using Meteor 1.0.3 and node 0.10.35 on a small Ubuntu Server 14.04 LTS (HVM), SSD Volume Type - ami-3d50120d EC2 instance.
Context
I know how to do server side debugging on my development box, just $ meteor debug and open another browser pointing to the url it produces -- works great.
But now, I'm getting a server error on my EC2 instance I'm not getting in development. So I'd like to set up a remote debug session sever side.
Also, I deployed to the EC2 instance using the Meteor-up package (mup).
EDIT
In an effort to provide more background (and context) around my issue I'm adding the following:
What I'm trying to do is, on my EC2 instance, create a new pdf in a location such as:
application-name/server/.files/user/user-name/pdf-file.pdf
On my OSX development box, the process works fine.
When I deploy to EC2, and try out this process, it doesn't work. The directory:
/user-name/
for the user is never created for some reason.
I'd like to debug in order to figure out why I can't create the directory.
The code to create the directory that works on my development box is like so:
server.js
Meteor.methods({
checkUserFileDir: function () {
var fs = Npm.require('fs');
var dir = process.env.PWD + '/server/.files/users/' + this.userId + '/';
try {
fs.mkdirSync(dir);
} catch (e) {
if (e.code != 'EEXIST') throw e;
}
}
});
I ssh'd into the EC2 instance to make sure the path
/server/.files/user/
exists, because this portion of the path is neccessary in order for the above code to work correctly. I checked the path after the code should have ran, and the
/user-name/
portion of the path is not being created.
Question
How can I debug remote server side code in a easy way on my EC2 instance, like I do on my local development box?
Kadira.io supports remote errors/exceptions tracking. It allows you to see the stacktrace on server side exceptions in the context of your meteor methods.
See https://kadira.io/error-tracking.html for more detail.
It seems in my case, since I'm using Meteor-up (mup), I can not debug per-say, but get access to the remote EC2 instance server console and errors by using command $ mup logs -f on my development box.
This effectively solves my issue with being blind on the server side remote instance.
It still falls short of actual debugging remotely, which speeds up the process of finding errors and performance bottlenecks, but it's all we have for now.
For someone who still searching:
#zodern added server-side debugging of meteor apps to great meteor-up tool:
https://github.com/zodern/meteor-up/pull/976
Do mup meteor debug in deployment dir and you will be almost set, just follow the text.
I am working on meteor framework and trying to upload images in one of my app using the code from the link
https://gist.github.com/3922137
Everything works good , except that it uploads the empty file in my public folder of app .
I checked console and it shows 503 error there after I select a file to upload
Here is the console screenshot
http://img40.imageshack.us/img40/2956/consolewl.jpg
It keeps on looping and the number of errors keeps on adding in console
I am using meteor on windows .
Does anyone has managed to get file uploads work in meteor on windows platform ? and if yes can you please share the code which worked for you .
Thanks
Aman
The reason you are getting a 503 is that when anything in the public folder changes meteor reloads. Because your uploads are going there the server is resetting. Change your code not to save it to public but rather somewhere else and you should see the error go away.
