Cannot decode refreshToken using JWT

[NordlingDev]

When calling firebase.getCurrentUser(), it will leave a promise with the user info such as refreshToken. I am trying to decode this token using firebase/php-jwt, but am unable to do that using the given refresh token.

Uncaught exception 'UnexpectedValueException' with message 'Wrong number of segments'

The error comes from the JWT, but it seems like Firebase plugin is handing out an invalid token?

UPDATE: After translating this to JavaScript, I got a valid token. Which btw is a lot longer than the refreshToken:

var currentUser = FIRAuth.auth().currentUser;

currentUser.getTokenForcingRefreshCompletion(true, function(idToken, error) {
  if(error) {
    console.log(error);
  } else {
    console.log(idToken);
  }
});

Is this on Android? How did you get the token in the first place?

@IvRRimum - Sorry, forgot to mention. This is iOS.

There was a method called getAuthToken that provided this but I somehow managed to remove it by mixing up my remotes. It's back in 3.7.0.
