Missing uid when using local emulator suite

See original GitHub issue

I’m currently trying to setup next.js authentication with this library and the firebase emulator suite. I had success connecting the next-firebase-auth with our cloud test instance but no success with the emulator. Every login attempt fails with an auth/argument-error where the uid is null.

Versions

next-firebase-auth version: ^0.14 Firebase JS SDK: ^8.9.1 Next.js: 12.0.7 Firebase Tools in Docker: 10.0.1

To Reproduce Steps to reproduce the behavior:

Setup Local Emulator Suite and Example Project
Configure Emulator Suite
Create firebase user using the emulator ui
Attempt a login

The exception occurs when calling BaseAuth.createCustomToken.

BaseAuth.prototype.createCustomToken = function (uid, developerClaims) {
  return this.tokenGenerator.createCustomToken(uid, developerClaims);
};

Error

errorInfo: {
  code: 'auth/argument-error',
  message: '`uid` argument must be a non-empty string uid.'
}

OK, thanks. I’ll investigate this when I can make the time, though that probably won’t be for a little while. Hopefully, others who have set up the emulator can weigh in here with suggestions.
