How to debug

[numbers1thru9]

Occasionally I will get an "Internal Error Has Occurred In The Application" but since it does not send the exceptions to the console or anywhere that I can see I cant find the error. The guide I didn't see any debugging instructions either. What is the best way to debug when these errors occur?

adding debug=True to start_server() will enable traceback printing in pywebio popup when internal error occurred
