Permissions error on log out

[kium-one]

Has your issue been reported?

• I have searched the existing issues and confirm it has not been reported.
• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

User goes to settings page, then navigates to a sub page, on that sub page they click on log out button (auth logout). When the user lands on the login screen again, a firebase permission error shows up.
When inspecting the error, it seems like a single-time query that was on the settings page is concerned.

I didn't touch that project's area in a while. The only thing that changed was me enabling deeplinks. Not sure if that's related.

Expected Behavior

Queries are disposed properly on log out.

Steps to Reproduce

1. Create root page with a query that requires the user to be authenticated (firebase permissions)
2. Create sub page and navigate there
3. Place a log out button.
4. When the user logs out and goes to login page, an error is shown.
   I didn't test on a blank project.

Reproducible from Blank

• The steps to reproduce above start from a blank project.

The problem seems to be project-specific, you have not shared a blank project reproducing the problem.
From the first sight this seems to be due to your firebase rules, for further investigation, please reach out to the FlutterFlow support using live chat or email (support@flutterflow.io) so you could dig deeper into the issue!

@SameerShahzad99 For what it's worth, I can replicate this.

Steps for me - first (mysterious) version:

• Go to Sign In page and sign in
• Land on homepage. Homepage does a couple of queries that depend on the user being signed in, as it does for OP.
• Hit Sign Out button
• Land on Sign in page
• See "insufficient permissions" error

So, I loosened up my permissions a little, and tried again.

Second (enlightening) version:

• Same steps, but on the last step (Sign in), the error changed to an error saying I needed to create a new index on my cars collection. This was a little confusing, as my Sign In page has no queries from the cars collection.

I realized that it was retaining the cars collection query from the Homepage somehow, and an index was required because the user was no longer signed in, so it wasn't limiting its query to the user's cars (cars in the user's cars subcollection), but it was looking at all cars (which it definitely should not do.)

If it helps, my cars query is happening as a Backend Query on a row that I use to display cards (each one with a car.) The query is not one-time. It will typically return 1-4 documents.

After some searching in an attempt to debug this, it seemed like OP's bug report has pretty much the same issue/symptoms. Hope this helps. I don't have time right now to set up a blank project (deadline impending), but I'll try after the deadline. Happy to provide any other info about my project if helpful.

*** UPDATE: I'm no longer seeing the error. I did not create the index. I did however turn caching on for the Backend Query. Strangely, I then turned caching off again, and the error did not come back, so hard to say definitively that the cache fixed it, but perhaps this may help y'all figure out what's going on.
