NoReverseMatch at reset_password_complete: Django PasswordResetConfirmView
I am using Django's default password reset views and forms to send an email to the user for them to reset their password via a link in the email.

Value nr 1 was picked during the makemigration: It is impossible to add a non-nullable field 'profile' to projects without specifying a default.
