Issue Description

So I have setup my Parse Server(5.2.0) and Dashboard(4.1.0) and I am using the JS SDK latest version to build a React Native app with Parse integration but queries respond with ParseError: 119 This user is not allowed to access non-existent class: Task. But Task class exists and if I update any field then the query works fine. Any ideas?

Steps to reproduce

Basic query responds with ParseError: 119 This user is not allowed to access non-existent class: Task. Task class exists

Actual Outcome

ParseError: 119 This user is not allowed to access non-existent class: Task.

Expected Outcome

Class Tasks values

Have you checked your class level permission in the dashboard?

[andresteves]

Class level permission is public read / write.

[dplewis]

In your Parse Server Configuration do you have allowClientClassCreation turned off?

[andresteves]

@dplewis Yes I have it off.

[dplewis]

Turning it on should fix your issue. See here

@dplewis but I want to read only from app side. Would that not enable classes to be editable and even created on client side?

[dplewis]

Can you update to the latest version of Parse Server?

[andre-sonect]

@dplewis I know this might be a dumb question but is there any problem on updating the version directly (meaning do I need to do a backup or anything) ?

[dplewis]

Depends on the changes from 5.XX to 6.XX may have some breaking changes.

[andre-sonect]

@dplewis does parse-server sleeps for some reason because I am trying the same now on a backoffice and it does login fine but then when trying to fetch a pointer inside _User class, it returns undefined.

try {
		await Parse.User.logOut();
		var usr = await Parse.User.logIn(req.body.email, req.body.password);
		usr = Parse.User.current();
		var query = new Parse.Query('Client');
		var client = await query.get(usr.get('clientId').id);     <-------- get('client').id returns undefined ----
		var flags = client.get('flags');
		
		if (flags.includes('****')) {
			res.redirect('/contents/welcome')
		}  else {
			res.redirect('/app/about')
		}
	} catch (error) {
		res.render('index', { error: 'Invalid username/password: ' + error })
	}
