On Authentication Triggers I Am Getting Displayname As Null

I want to use users data on authentication trigger. But when I am using them it gives me null. What is wrong with my code? exports.sendWelcomeMessage = functions.auth.user().onCrea

Solution 1:

I speculate you are creating the user and then setting the display name (eg via 2 calls).

onCreate triggers as soon as the user is created, eg createUserWithEmailAndPassword.

When you call updateProfile to set the displayName, the onCreate event would have already been triggered.
