I got this to work by:
UN-checking: AutoGenerateKey and SigninRequired
Then one of the two combinations of details I provided actually WORKED!
Why is it that we too often have to resort to trial-and-error to make stuff work ?
Firebase has a lot of configuration options & flexibility and with that also comes some complexity unfortunately.
All I'm getting now when I try to connect is a 403 error, although the tokens are being generated.
Error code : 403
Error message : Permission denied on resource project MyApp.
Error status : PERMISSION_DENIED
It's not coming from the Rules.
Any ideas?
Without any further details, it is impossible to provide useful feedback.
I would think that you haven't given access to the project to the account with which you sign-in with Google.
unfortunately, that's all the detail I'm getting from the component.
