Error in step 3.(other environment)

[shiotani-bit]

In the different environment, I followed the steps in the order listed in the Quick Start, but I get an error in step 3.

python -m src.start_task -a

When I run the above command, it outputs TypeError: issubclass() arg 1 must be a class.

Execution log is following.

python -m src.start_task -a
