Review comment:
@showuon Because it's all checking for Not Controller error, can we put
the logic for check NotControllerError into the same method? So the else if
argument is a little bit cleaner. But this is only a small tip, and it's up to
you to decide if you need to do it. This is a great discovery. You have solved
my confusion when I met UNKNOWN_SERVER_ERROR. Thank you.
