error SignedOutException, for a firestore document that does not require authentication.

[Justus-M]

Firstly huge thanks for this library.

I get the following error when trying to access a firestore document while the user is not authenticated.

It happens for both streaming and just getting the document.

Handling error gRPC Error (code: 13, codeName: INTERNAL, message: Error making call: SignedOutException: Attempted to call a protected resource while signed out, details: null, rawResponse: null, trailers: null) using FirestoreGateway._handleError

But here is the relevant firestore rule:

    match /config/{doc} {
      allow read: if true;
    }

Here is the full stacktrace

It looks like you are just blocking all unauthenticated requests, which is not always wanted.

If a dev doesn't want to allow access without authentication, they can set that up in the Firestore rules. I think rather than blocking all unauthenticated requests, it would be better to just leave that to the firestore rules.

Thanks for the report.
On the surface this seems to be a bug, but I'm not currently equipped to test and debug it.

Contributions are welcome though, if you want to take this challenge yourself :-)

Hi! I did actually see if I could fix it initially but ended up just going for a workaround yesterday.

I wanted to stream the app version number before the user logs in so I can force them to update if necessary (that's what I was doing with flutterfire). I now host a Json file instead, and periodically make an http request to read it.

I just had another look inside the firedart library but couldn't really wrap my head around where this error came from. When you do figure it out, I'll be very curious to understand the fix!

We got the same issue, Please help us with the quick fix.

My workaround was actually not to use firestore. I only needed to stream one value before authentication, so I've put that value in a json file on the web and im reading it in a loop via Http requests.
