When attempting to use Mail Debugger I was getting the following error:
TypeError: Argument 1 passed to _user_registrationpassword_mail_debugger_form() must be of the type array, null given, called in mail_debugger/includes/mail_debugger.callback.inc on line 58 in _user_registrationpassword_mail_debugger_form() (line 17 of user_registrationpassword/includes/user_registrationpassword.mail_debugger.inc).
I discovered that the Type declaration on _user_registrationpassword_mail_debugger_form was causing the error, I also removed them from the validation and submit functions too.
