All Upper - syntax error

I would like to give some feedback about ...

From: https://py.checkio.org/mission/all-upper/solve/

HTTP_USER_AGENT:

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.122 Safari/537.36

There seems to be a syntax error in verification:

"input": [''DIGITS 123 ''],, ^,SyntaxError: invalid syntax,

resulting in:

ErrUchIsDown: You process has been killed because of using too much resources
