Parse-server: You need to call Parse.initialize before using Parse

[fuatcoskun]

I am trying to migrate my Parse application to my local computer as backend instance and using MongoLab MongoDB. I have downloaded https://github.com/ParsePlatform/parse-server-example and configured with my appId, masterKey, databaseURI, etc. as follows :

var api = new ParseServer({
  databaseURI: databaseUri || 'mongodb://fuatcoskun:[email protected]:19268/database',
  cloud: process.env.CLOUD_CODE_MAIN || __dirname + '/cloud/main.js',
  appId: process.env.APP_ID || 'appId',
  masterKey: process.env.MASTER_KEY || 'masterKey', //Add your master key here. Keep it secret!
  clientKey: process.env.CLIENT_KEY || 'clientKey', //Add your client key here.
  restAPIKey: process.env.REST_KEY || 'restApiKey',
  serverURL: process.env.SERVER_URL || 'http://localhost:1337'  // Don't forget to change to https if needed
});

After running "npm start" my backend service starts to listen port 1337 :

> [email protected] start /Users/fuat/parseLocal/parse-server-example
> node index.js
parse-server-example running on port 1337.

I have a huge code base but I added a dummy function for easing basic check before calling actual functions.

Parse.Cloud.define("deneme", function(req,res) {
    res.success("result : " + Constants.LIMIT);
});

I can call this function via following curl command:

`curl -X POST 
-H "X-Parse-Application-Id: appId"
-H "X-Parse-REST-API-Key: restApiKey" 
-H "Content-Type: application/json"
-d '{}' http://localhost:1337/parse/functions/deneme`

Result is successful :
{"result":"result : 10"}

Problem is that, I am getting the following error when I call some of my functions which make some stuff with ParseQuery class like querying database etc.

Uncaught internal server error. [Error: You need to call Parse.initialize before using Parse.] Error: You need to call Parse.initialize before using Parse.

At Storage.js:82:13 there is APPLICATION_ID check as shown below :

if (!_CoreManager2['default'].get('APPLICATION_ID')) {
   throw new Error('You need to call Parse.initialize before using Parse.');
}

I was expecting that APPLICATION_ID, MASTER_KEY and similar parameters I defined with ParseServer instance should already be set. If I call

Parse.initialize("appId", "javascriptKey", "masterKey");

just top of my function on cloud code, it works as expected without error. But this is not a good workaround. How can I handle this difficulty? What should I do to initialize Parse successfuly before my function calls?

Additionally the same code base is working on Parse cloud without an extra Parse.initialize(..) call on top of functions. Most probably there is a missing initialization step in the https://github.com/ParsePlatform/parse-server-example/blob/master/index.js

In your cloud code, remove any definition of Parse. Do not require parse. It is pre-initialized and available to you as a Global and must not be re-defined.

Thanks for you reply, but I am getting this error if I try to use "Parse" directly without "require(parse/node).Parse" definition.

Users.PrivateUserClass = Parse.Object.extend("PrivateUser");
