-[X] You've searched through existing issues. Chances are that your issue has been reported or resolved before.

Environment Setup

Running Parse Server on Localhost.
Downloaded code from Amazon Elastic Beanstalk

Steps to reproduce

Running any cloud function with a query. Normal cloud function works well. Called using node script.

Logs/Trace

I found other issue #651 (comment) which is currently closed. However, even after following the steps and setting up serverURL problem doesn't resolve. XHR failed with status 0.

[guptasachin25]

@gfosco you worked on previous issues. Can you help resolve this one.

[gfosco]

Can you provide the code for your function? (or the whole cloud code file...)

[gfosco]

Discussed over email, problem is the script is overwriting the Parse global which definitely breaks everything.

I am using self hosted parse-server and not able to use cloud functions since I have enabled HTTPS, if I revert it back to HTTP it works as expected.

Also he problem is only with those cloud function which have Parse.Query, if i create a function simply return "Hello" as response it works on both HTTP and HTTPS.

I am getting following error message when run a cloud function which have Parse.Query code.

{
"code": 141,
"error": "XMLHttpRequest failed: "Unable to connect to the Parse API"--100"
}

can anyone tell me how can I fix this?

I am also facing the same issue. Any pointers with that ? w3care25, did you end up fixing it ?

@chandanthakur You need to add process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0"; in you instance file of parse server if you are running into similar issue

[w3care25]

@ckarmy You need to create an instance with SSL something like below:

_var privateKey = fs.readFileSync( 'path to ssl key ( .key ) file' );
var certificate = fs.readFileSync( 'path to ssl crt ( .crt ) file' );
var cabundles = fs.readFileSync( 'path to ssl cabundle ( .cabundle ) file');

https.createServer({
key: privateKey,
cert: certificate,
ca: cabundles
}, app).listen(port);_

Don't forgot to add var https = require('https');

@w3care25 adding in the process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0" line still doesn't fix it. Any other ideas? thanks.

[w3care25]

If you have configured everything correctly. You may need to restart your server after adding this line.

If you are still having this after server restart, Could you please share you instance file code ( after replcing your confidential credentails with dummy details)?

[willyyang]

@w3care25 I have restarted the server but I am still getting the same results.

// SERVER_URL is set to https://APPNAME.herokuapp.com/parse through Config Variables
// MONGODB_URI is set through Config Variables

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

var databaseUri = process.env.DATABASE_URI || process.env.MONGODB_URI;

if (!databaseUri) {
  console.log('DATABASE_URI not specified, falling back to localhost.');
}

var api = new ParseServer({
  databaseURI: databaseUri || 'mongodb://localhost:27017/dev',
  cloud: process.env.CLOUD_CODE_MAIN || __dirname + '/cloud/main.js',
  appId: process.env.APP_ID || 'xxx',
  masterKey: process.env.MASTER_KEY || 'xxx', //Add your master key here. Keep it secret!
  serverURL: process.env.SERVER_URL || 'http://localhost:1337/parse',  // Don't forget to change to https if needed
  liveQuery: {
    classNames: ["Posts", "Comments"] // List of classes to support for query subscriptions
  }
});

var app = express();
app.use('/public', express.static(path.join(__dirname, '/public')));
var mountPath = process.env.PARSE_MOUNT || '/parse';
app.use(mountPath, api);

//Required to receive JSON body from POST
app.use(bodyParser.json()); // support json encoded bodies
app.use(bodyParser.urlencoded({ extended: true })); // support encoded bodies

// Parse Server plays nicely with the rest of your web routes
app.get('/', function(req, res) {
  res.status(200).send('I dream of being a website.  Please star the parse-server repo on GitHub!');
});

// This will enable the Live Query real-time server
var port = process.env.PORT || 1337;
var httpServer = require('http').createServer(app);
httpServer.listen(port, function() {
    console.log('parse-server-example running on port ' + port + '.');
});
ParseServer.createLiveQueryServer(httpServer);

Hitting the sample hello function works but all of mine return the XMLHttpRequest failed: \"Unable to connect to the Parse API\"--100 error.

Thank you very much for your help.

backup you instance file and try following code

var express = require('express');
var ParseServer = require('parse-server').ParseServer;
var app = express();
var fs = require('fs');

var api = new ParseServer({
databaseURI: 'mongodb://localhost:27017/dev', // Connection string for your MongoDB database
cloud: '/home/myApp/cloud/main.js', // Absolute path to your Cloud Code
appId: 'myAppId',
masterKey: 'myMasterKey', // Keep this key secret!
fileKey: 'optionalFileKey',
serverURL: 'http://localhost:1337/parse' // Don't forget to change to https if needed
});

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";
// Serve the Parse API on the /parse URL prefix
app.use('/parse', api);

app.listen(1337, function() {
console.log('parse-server-example running on port 1337.');
});

Make sure you are not accessing you sever with https (SSL enabled). If you need to access your server with https then you will have to add following

var https = require('https');

var privateKey = fs.readFileSync( 'path to ssl.key' );
var certificate = fs.readFileSync( 'path to ssl.crt' );
var cabundles = fs.readFileSync( 'path to ssl.cabundle');

https.createServer({
key: privateKey,
cert: certificate,
ca: cabundles
}, app).listen(1337);

and remove

app.listen(1337, function() {
console.log('parse-server-example running on port 1337.');
});

@w3care25 Im hosting this on heroku. Wouldn't serverURL: 'http://localhost:1337/parse' and databaseURI: 'mongodb://localhost:27017/dev' point to my local ?

[w3care25]

You can use Heroku credentials here

[w3care25]

@willyyang were you able to fix your issue ?

[willyyang]

@w3care25 I'm looking for another alternative still because I don't to buy a certificate
