clipper: Prometheus Related Error When Starting Connection

I’m running clipper on python 3.6 in linux 18.04. I’m running clipper from a container and I share the current docker.sock via a volume. When starting a connection to clipper I get the following error:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/dist-packages/docker/api/client.py", line 261, in _raise_for_status
    response.raise_for_status()

    raise HTTPError(http_error_msg, response=self)

During handling of the above exception, another exception occurred:

Do you have some idea of what may be the cause of this error? I looked up related issues but all I found was the same error being caused due to clipper being ran in Windows 10. #688

Any help would be highly appreciated.
