request.auth is null for what should be a valid request with self-made custom token [Firestore emulation]

[akauppi]

[REQUIRED] Describe your environment

• Operating System version: macOS 11.2.3
• Browser version: Chrome 89
• Firebase SDK version: 9.0.0-beta.1
• Firebase Product: firestore

[REQUIRED] Describe the problem

The context is emulation (development). In production everything is nice.

In my security rules, request.auth is null though it should not.

I've authenticated in web client like this:

        await signInWithCustomToken( auth, JSON.stringify({ uid }) )
          .then( creds => {
            console.debug("Signed in as:", { creds });
          })
          .catch( err => {
            console.error("Sign-in failed:", err);
          });

I can see in the browser console that the sign-in is successful.

firestore-debug.log shows this warning:

Apr 15, 2021 1:19:05 PM com.google.net.webchannel.server.common.CorsFilter populateCustomHeaders

Can I do something about that?

But the real problem is that I cannot subscribe to changes of the connection guarded by a rule that uses request.auth.uid. I've established that request.auth is null, by playing with the rule.

Steps to reproduce:

$ git clone git@github.com:akauppi/GroundLevel-firebase-es.git
$ cd GroundLevel-firebase-es
$ git checkout interim   # this branch
$ npm install

$ cd packages/app
$ npm install
$ npm run dev

Open http://localhost:3000/?user=dev and observe the contents of the firestore-debug.log

Expected:

Actual:

As above, without the project entry.

This looks like a bug or two, to me. Things used to work long ago. The current code is based on 9.0.0-beta.1 and I'm no longer able to try with 8.x APIs. Not sure which change has started this problem.

Thanks for any help!

@akauppi Something similar happened to me yesterday. I have downgraded to firebase: 8.3.0 and the issue was gone (make sure to clean up package-lock.json and node_modules). Seems like 8.4.0 also has the same issue.

[akauppi]

@ANDREYDEN Thanks for the extra info. In my case, I’m (happily) stuck with the 9.x beta (different API) so no downgrade possibility, but I trust Firebase to look into this, and suggest a fix.

@akauppi what version of the Firebase CLI are you using? v9.9.0 includes a critical bug fix around parsing auth headers:
https://github.com/firebase/firebase-tools/releases/tag/v9.9.0

[akauppi]

@samtstern I'm using the latest, 9.10.0 so it's not that.

Was this closed because it was fixed? I'm running 9.10.2 and I have the same issue.

[akauppi]

@Davste93 I received the fix with some update. Are you on firebase-tools 9.10.2 that has Firestore emulator 1.11.15?

Hi!
First, I want to say thanks! you saved me, i had been looking for two days how to solve it.
I work with IONIC 5 and Capacitor. I leave me package.json to whoever may be interested.

This bug is happen to a lot of people but is very difficult find the reason and this forum.

again, thanks a lot to all!
