Python google cloud function deployment failure - websockets

I am trying to deploy a python script from Google source code and it is failing when attempting to import create_connection from the websockets library.

Here is the top of my script. It fails during import of the gemini package, which in turn is importing websockets:

import json
import os

from gemini import PrivateClient

and my requirements.txt

gemini-python==0.2.1

The Google Cloud Functions log shows this error:

This script runs on my Mac using Python 3.8. Not sure what to do as this seems environment specific. Any help is appreciated.

Solution

  • Cloud Functions does not support WebSockets.

    You may want to consider an alternative compute service such as Cloud Run which does
