Error when opening docstring

[uprokevin]

Is it related to those python flags ?

# Keeps Python from generating .pyc files in the container
export PYTHONDONTWRITEBYTECODE=1   

# Turns off buffering for easier container logging
export PYTHONUNBUFFERED=1          

#### Remove Assert and Docstring
export PYTHONOPTIMIZE=2 

Code:

        if "s3:/" in dirs3:
          session = aws_get_session()
          with open(dirs3, mode=mode, transport_params={'client': session.client("s3")}  ) as fp:
             ddict = json.load(fp)

Yes, I think this is the cause:
