I'm using Firebase and getting an error which leads to perpetual loading on my loginView.
Here is the error I get in the console when I try to create an account (it save the info to the database successfully);

Once a user taps the create account button the app should connect to Firebase storage to save the user info and image and then load to the mainView()
