updateCurrentUser failed: First argument "user" must be an instance of Firebase User or null.

Describe your environment

• Operating System version: Mac
• Browser version: Google Chrome Version 71.0.3578.98
• Firebase UI version: "react-firebaseui": "^3.1.2"
• Firebase SDK version: "firebase": "5.7.1"

Describe the problem

I’m using the https://github.com/firebase/firebaseui-web-react wrapper My implementation it seems to do the login properly on firebase (as i can see the mail logged on “Users” but on my react app I’m getting this error all the time

updateCurrentUser failed: First argument "user" must be an instance of Firebase User or null.  Dismiss

No signInSuccessUrl redirection or signInSuccessWithAuthResult callback works after this error

    signInSuccessUrl: '/',
    callbacks: {
      signInSuccessWithAuthResult: function(authResult, redirectUrl) {
        console.log(authResult)
        console.log(redirectUrl)
        return true
      }
    }

I have no clue about how to debug this or what would be the error

Any ideas?

I hit this error, and the reason was we had two copies of Firebase (one we were including manually, one which npm was pulling in). That caused this bug because for some reason it was using the manual one we specified to invoke the FirebaseUI React component and then calling updateCurrentUser() in the underlying npm version of Firebase (and thus checking the type there). Both versions of Firebase were 5.7.1 so it wasn’t a versioning issue, it was that we had two copies of Firebase and the component wasn’t consistent about which one it used (which I’d argue is a bug in FirebaseUI or the React-FirebaseUI module, but I ain’t dying on that hill).

Same problem here, but this happens to me only when using typescript. I made a test with similar code with javascript with the same environment and same code and it did work.

The actual firebase auth works. A new user is been created to firebase app but then something goes wrong. I have not yet been able to find the exact place where.
