How to run firebase blocking function (beforeUserCreated) in emulator suite?

After searching for numerous hours all over the web and asking ChatGPT, I have found no solution.

I have a Firebase Project (Web App) and I am using Gen2 Javascript Node for Firebase Functions. I have enabled Firebase Auth with Identity Platform in my project.

I am ONLY using emulators currently.

The problem I’m having is that the beforeUserCreated event (blocking function) is not being called in my emulator.

All other functions work perfectly. Users get created (when they shouldn’t due to the blocking function) and there are no errors in the logs.

My index.js file looks like this:

import * as v2 from "firebase-functions/v2";

import {
    beforeUserCreated,
    beforeUserSignedIn,
  } from "firebase-functions/v2/identity";

export const helloworld = v2.https.onRequest((request, response) => {
    response.send("Hello from Firebase!");
});


export const beforeusercreated = beforeUserCreated({ region: 'europe-west1' }, (event) => {
    const user = event.data;
  // Only users of a specific domain can sign up.
    if (!user.email || !user.email.endsWith("@example.com")) {
        throw new HttpsError("invalid-argument", "Unauthorized email");
    }
  });

I also get this in the function logs in the emulator:

✔  functions[us-central1-beforeusercreated]: providers/cloud.auth/eventTypes/user.beforeCreate function initialized (http://127.0.0.1:5101/univus-9457e/us-central1/beforeusercreated).

Can someone please help me out here. Has anyone found a solution to this?

I’ve tried changing the function names, nothing changes. There are no errors, no documentation anywhere!
