My submission always failed

I am interested in this challenge:
I tried to submit my file but the Status result is always “Failed” with the following Stderr message.

Traceback (most recent call last):
File “/code/scripts/workers/”, line 538, in run_submission,
File “/tmp/tmp7pjn72f_/compute/challenge_data/challenge_97/”, line 152, in evaluate

KeyError: ‘86505f3c38e84f2fbd18097bf5aa043f’

Thank you
