I encountered the same error in Task1 as well.
Error:
Traceback (most recent call last):
File "/worker/worker.py", line 330, in run
if input_rel_path not in bundles:
TypeError: argument of type 'NoneType' is not iterable
output is also empty:

Additionally, the same submission returns both a failed response and finished response:
