After logging in user server side through cloud code ParseUser cannot be set using returned User object

[SexyBeast007]

Issue Description

After logging in on the server side with credentials, I cannot set the ParseUser that was used to make the cloud call, as a logged in user with the returned User object.

Steps to reproduce

I will be showing two different ways I have attempted this.

/// Cloud login method - SERVER SIDE
Parse.Cloud.define("login", async function(request, response) {
  const username = request.params.username;
  const password = request.params.password;
  // Login
  try{
    let user = await Parse.User.logIn(username, password);
    if (user) return user
  } catch (error) {
    throw new Error(error.message);
  }
});

/// Cloud login method - CLIENT SIDE
  Future<ParseResponse> login(WidgetRef ref, String username, String password) async {
    ParseUser user = ParseUser(username, password, null);
    final ParseCloudFunction cloudLogin = ParseCloudFunction('login');
    final Map<String, dynamic> credentials = <String, dynamic>{
      'username': user.username,
      'password': user.password,
    };
    final ParseResponse loginAttempt = await cloudLogin.execute(parameters: credentials);
    
    /// ATTEMPT 1
    ref.read(authenticationServices).setAuthorizedUser(user);

    /// ATTEMPT 2
    ref.read(authenticationServices).setAuthorizedUser(loginAttempt.result);
    
    return loginAttempt;
  }

Actual Outcome

ATTEMPT 1

SUCCESSFUL LOGIN PAYLOAD

Payload: {
username: 001, 
email: 0001@gmail.com,

}

ATTEMPT 2

LOGIN FAILURE

error:
type '_InternalLinkedHashedMap<String, dynamic>' is not a subtype of ParseUser

Expected Outcome

I expected to be able to assign return object from Login payload as ParseUser or to have it happen automatically as in ATTEMPT 1 above, neither work.

Environment

• Flutter: >=2.15.1 <3.0.0

Parse Flutter SDK

• SDK version: 1.0.1
• Operating system version: MacOS Big Sur 11.6.2

Server

• Parse Server version: 4.5.0

I have also tried the following, setting ParseUser explicitly with all the parts of the payload.

late ParseUser? _authorizedUser;
  ParseUser? get authorizedUser => _authorizedUser;
  void setAuthorizedUser(Map<String, dynamic> user) {
    _authorizedUser = ParseUser(
      user['username'],
      user['password'],
      user['email'],
    )
      ..set('sessionToken', user['sessionToken'])
      ..set('objectId', user['objectId'])
      ..set('className', user['className'])
      ..set('name', user['name'])
      ..set('createdAt', user['createdAt'])
      ..set('updatedAt', user['updatedAt'])
      ..setACL(user['ACL']);
  }

I get an error traced back to ParseCoreData().sessionId being null

Try calling this line of code after setting the user data.

ParseCoreData().setSessionId(user['sessionToken']!);

The sessionToken is being configured only in the signin and signup methods of the SDK.

You created a custom process, you need to set it manually.

That did it @RodrigoSMarques, thank you very much! I appreciate the expertise!

And yes, I am creating my own system. I am taking security a step further. For certain threat actors HTTPS should no longer be trusted, therefore I will be locking down all CLPs and creating a sort of sub-https hybrid encryption system for all cloud code calls including login and logout. This is the last piece of the puzzle to enable this secure system. Thank you
