Emulator: auth functions not triggered

It seems that the firebase functions based on auth events (in my case functions.auth.user().onCreate) are not triggered within the emulator suite. In Emulator UI i’m able to see that my auth function is initialized correctly but nothing happens when a user is created (from client side with auth.createUserWithEmailAndPassword() method)

I set the required env variables (FIREBASE_AUTH_EMULATOR_HOST and GCLOUD_PROJEC) when launching the emulator

My dependencies are up to date : firebase-tools 8.16.2 firebase-admin: 9.4.1 firebase-functions: 3.11.0

Note : regular firebase functions are triggered properly in the emulator.

I am having the same issue.

Other Functions are working “https.onCall” Debugger jumps to breakpoints etc, but auth.user().onCreate is not firing, don’t know if the emulator suite emulates this behaviour but auth.user().onCreate also does not fire when creating a user from the emulator dashboard.

Hi, An update from my side, after updating firebase-tools the onCreate function is firing again.

Also one thing to note is that firebase-ui is not compatible with the auth emulator the firebase-ui team is still working on getting it to work. When using Firebase-ui it will send all comms to the configured project directly.

NB: So when you use firebase-ui all auth requests will bypass the emulator (even if useEmulator() is called) and thus the local onCreate functions will not get called.
