I think Relation doesn't work.

[facuparedes]

Hi! I'm trying to use Parse Server in my new app. I have the following db schema:

As you can see, class Chats has columns: Users (a Relation), and Messages (another Relation). However, when I try to do a simple request:

ParseResponse res = await ParseObject('Chats').getAll();
print(res.results);

I get the following log:

Payload: [{"className":"Chats","objectId":"lr6D880lmt","createdAt":"2020-08-11T22:46:51.609Z","updatedAt":"2020-08-12T05:36:36.234Z","users":{"__type":"Relation","className":null,"objects":null},"messages":{"__type":"Relation","className":null,"objects":null}}]

Pay attention to "users" and "messages" response. Both returns "className":null. That should not happen. At least, with JS and Node.JS, I don't get any "null" value.

Furthermore, I need to get Chats class filtered by 'email' column from Users on 'user' column. And get all messages from 'messages' column.

So, I tried get all messages with:

ParseObject obj = (await ParseObject('Chats').getAll()).results[0];

ParseRelation rel = obj.getRelation('messages');

rel.getQuery().query().then((value) => print(value.results));

However, I got this Parse Request:

I/flutter ( 6813): ╭-- Parse Request
I/flutter ( 6813): curl -X GET -H 'user-agent: Flutter Parse SDK 1.0.26' -H 'X-Parse-Application-Id: **************' -H 'X-Parse-Master-Key: **************' https://parseapi.back4app.com/classes/null?where=%7B%7D
I/flutter ( 6813):
I/flutter ( 6813):  https://parseapi.back4app.com/classes/null?where={}
I/flutter ( 6813): ╰--

As u can see, request's url is: classes/null, so obviously, I got a null response:

I/flutter ( 6813): ╭-- Parse Response
I/flutter ( 6813): Class: null
I/flutter ( 6813): Function: ParseApiRQ.query
I/flutter ( 6813): Status Code: 200

I/flutter ( 6813): ╰--

Can you help me ?
