Resolution: Not A Bug
Hi, [~Jason_H]
I aggree with [~yunta] , this exception is only be thrown when you change your
serializer related info which may cause incompatibility.
You could check the logic in [1].
I just closed it because it seems not a bug and no response beyond one year.
Please reopen it if we missed something.
