Answer by Chris for AngularFire Missing or insufficient permissions on login, works after refresh

I was able to solve the error by replacing the standard subscription with a switchMap

constructor(  private angularFireAuth: AngularFireAuth,  private firestore: AngularFirestore,) {  this.angularFireAuth.authState    .pipe(      switchMap((authUser) =>        authUser          ? this.firestore.collection('user').doc(authUser.uid).collection<Repository>('repositories').valueChanges()          : of([])      )    )    .subscribe(this.repositories$);}

I think the root of the problem was with the firebase listener trying to fetch documents during/after the logout process which was causing it to error out.

This would explain why refreshing the page between login sessions solves.

Awkward.
