[firebase_auth]: Errors from 'beforeUserSignIn' type blocking functions get clobbered into [firebase_auth/unknown_error] #17592
Description

Which plugins are affected?
Auth
Which platforms are affected?
Windows
Description
When signing in with email and password, my project has a 'beforeUserSignIn' blocking function running before logging in that throws an HttpsError. On android/ios/web, throwing an HttpsError within the blocking function can be detected by the client attempting login, with it able to read the contents (i.e. that the HttpsError is 'failed-precondition').
On Windows, errors from the blocking function are clobbered into 'unknown-error' and any extra data in the HttpError is inaccessible.
Login when the blocking function immediately returns without error works as intended.
Reproducing the issue
Using the example project on Windows, sign in with email and password whilst a blocking function has been configured and deployed.
You may need to configure the function in the Firebase Console at Authentication > Settings > Blocking Functions.
I was able to replicate the issue with this cloud function deployed.
min-viable-blocking.js
import { HttpsError, beforeUserSignedIn } from "firebase-functions/v2/identity";
import { setGlobalOptions } from 'firebase-functions/v2'
const functionConfig = {
region: "asia-south1",
concurrency: 60,
minInstances: 0,
maxInstances: 10,
cpu: 1.0,
};
setGlobalOptions(functionConfig);
export const beforeSignIn = beforeUserSignedIn( (event) => {
throw new HttpsError(
"failed-precondition",
"error message for the client to read",
{'usefulData': 'drink some water'}
);
});
For debugging purposes, I also edited firebase_auth/example/lib/auth.dart to catch, log and rethrow auth.SignInWithEmailAndPassword() on line 479.
