@HCZuo it was nice to meet you in Community Orientation the other day 
I wonder if the root issue here is related to this long standing product request around having more robust error logging in Tulip? Event log to record Tulip error messages
If you think this would solve your need, go ahead and vote on that request!
If your preferred solution here is having the ability to test published apps without affecting the published app itself, I can make this thread into a separate product suggestion for the team to consider.
