Issue Description

After adding the LiveQuery server and set it to watch _Session class in the config.json to start the server, If you are already logged in you get live updated from the session without any issue, but if you are logged out and you try to log in you won't be able to do it.

Steps to reproduce

Add the _Session class to the LiveQuery server:
"liveQuery": {
"classNames": ["_Session"]
},
"startLiveQueryServer": true,

Actual Outcome

You get the following error on the server :
error: Uncaught internal server error. Cannot modify readonly attribute: sessionToken

Expected Outcome

Perform log-in without any issues.

Thanks for reporting!

Could you submit a PR with a failing test to demonstrate the issue?

Hi, thank you for your quick answer!
Should I clone the project and submit a PR? I have installed the server through npm and I am starting it using a config.json file!

[mtrezza]

Yes, you could just fork the repo, clone it locally and add a test. Here is the technical guide, and a great blog post that may be easier to start if this is your first PR.

Here is the PR
I got the same issue when I run the test using npm run coverage

[mtrezza]

Does #7554 close this issue?

[dblythy]

Yep!

LiveQuery triggers for the Parse.Session can be used on master. Note that authData and sessionToken are stripped out for security purposes.

@Meglali20 thanks for opening this issue and providing the PR with the failing test!

Hi, @mtrezza @dblythy
After updating Parse to the latest release (4.10.4) it seems that the issue still persists, can't perform login when Live query is watching _Session.

Hi @Meglali20, please try 5.0.0 alpha or later.

https://github.com/parse-community/parse-server/releases/tag/5.0.0-alpha.1

[mtrezza]

Alternatively / additionally, please feel free to open a PR to backport the fix to release-4.x branch.

[Meglali20]

@dblythy
using now parse-server@5.0.0-alpha.3
The issue is fixed, can perform login now and watch over the session, but I have one question, is it normal that sometimes it does perform login and doesn't create a session token? I had to try multiple login attempts sometimes it creates sometimes doesn't.
