With traceback.format_tb
, tb_string is an array while make_fail_app is expecting a string so if you have an error somewhere say in your wsgi file, you get this printed in the console instead showing the real error on the webpage

it turns out format_exc
takes a limit arg not a traceback, so this tb_string = ''.join(traceback.format_tb(exc_tb))
should fix the ...is not a byte
error but gunicorn will not display the original IndentationError
and display
