The type 'FirebaseAuth' cannot be assigned to type 'Auth'

Recently, after updating my project dependencies, I encountered the following error:

ERROR in src/app/services/auth/auth.service.ts(19,5): error TS2322: Type 'FirebaseAuth' is not assignable to type 'Auth'. Types of property 'app' are incompatible. Type 'FirebaseApp' is not assignable to type 'App'. Property 'messaging' is missing in type 'FirebaseApp'.

Screenshot of the error https://i.sstatic.net/Arx6f.png

The code at line 19.5 looks like this:

this.auth = angularFireAuth.auth;

Screenshot of the code https://i.sstatic.net/cLQQV.png

List of dependencies:

"dependencies": {
    "@agm/core": "^1.0.0-beta.2",
    "@angular/cdk": "^5.2.2",
    ...
    "zone.js": "^0.8.20"
  },

Any ideas on what might be causing this issue? Thank you!

Answer №1

There might be an issue with the version you are currently using, as there have been significant changes.

constructor(af: AngularFire) {
  af.database.list('foo');
  af.auth;
}

The updated code should now look like this:

constructor(db: AngularFireDatabase, afAuth: AngularFireAuth) {
  db.list('foo');
  afAuth.authState;
}

For more information, please refer to: https://github.com/angular/angularfire2/blob/master/docs/version-4-upgrade.md

Answer №2

It appears that there may be an error in the assignment of a value, possibly related to firebase.auth.Auth. I recommend reviewing your environment file or the file where firebase.auth.Auth is defined for any potential mistakes. Unfortunately, without additional code it is difficult to provide specific debugging assistance.
