firebase create user by email not returning displayName using ui 2.3.0

seeing this issue closed several times in here, I am little shocked I have to post this issue.

using a simple firebase function, and using code very similar to the example here: https://firebase.google.com/docs/reference/functions/functions.auth.UserBuilder#onCreate

and using the sign in by email method on the firebase ui, and having the user sign up with first and last name,

my firebase function:

exports.createAccount = functions.auth.user().onCreate(function(event) {
	const data = event.data;
	console.log(data);
});

and the firebase function log shows me:

{ email: '[e-mail]',
  metadata: 
   { createdAt: 2017-07-28T14:29:08.000Z,
     lastSignedInAt: 2017-07-28T14:29:08.000Z },
  uid: 'xxxxxxxxxxx' }

where is yoda’s displayName (should be: Yoda Yo) which he entered in firebase ui?

And, so if I used the entire example in the link I posted above, how am I supposed to send yoda a personalized sign up email using his first name, when firebase ui doesn’t even return it?

I have a functional setup using a delay, but it does create a race condition. It seems a nicer solution would be to add an onUpdate trigger on the UserBuilder object (maybe this is already on a todo list somewhere?).

functions.auth.user().onUpdate(...)

okay then. thanks for this new info.

how about somewhere, the firebase team mention in ui or user creation documentation that email sign up does not act as expected or the same as other provider sign up. or fix it so they all work the same, ie don’t return a user until all profile info like displayName is ready.

in the meantime - any suggestion HOW to actually get the user displayName upon creation from email sign up using ui?

Update: nevermind, able to pull user info with a promise after email signup:

exports.createAccount = functions.auth.user().onCreate(function(event) {
	const data = event.data;
	console.log(data);
	admin.auth().getUser(data.uid)
  .then(function(userRecord) {
    console.log("Successfully fetched user data:", userRecord.toJSON());
  })
  .catch(function(error) {
    console.log("Error fetching user data:", error);
  });
});

functions console shows displayName:

Successfully fetched user data: { uid: 'xxxxxxxx',
  email: '[e-mail]',
  emailVerified: false,
  displayName: 'yoda yo',
  photoURL: undefined,
  disabled: false,
  metadata: 
   { lastSignedInAt: 2017-07-29T12:50:54.000Z,
     createdAt: 2017-07-29T12:50:54.000Z },
  providerData: 
   [ { uid: '[e-mail]',
       displayName: 'yoda yo',
       email: '[e-mail]',
       photoURL: undefined,
       providerId: 'password' } ] }
