Firebase Facebook Authentication Error with openFB in Ionic

Question

I can successfully access the facebook userdata via the OpenFB API, but when I try to use:

var auth = $firebaseAuth(ref);
auth.$authWithOAuthToken("facebook", accessToken)

to authenticate the user through Firebase, I get the following error:

Firebase Auth Error

I've tried adding several OAuth redirect URIs in the Facebook developer console:

Facebook O AUth Settings

I'm using the correct App ID and App Secrect from Facebook. Any ideas?
