I am working on a Google App and have an issue when I deploy it. The project contains two services website and worker. The website acts as a front page and the worker is run through a cron and has its page hit every 5 minutes.
The issue I'm having is that when running them locally both services run fine. Once I deploy with gcloud the application returns an error in the Logs Console.
The error is: ImportError: cannot import name 'vision' from 'google.cloud' (unknown location)
It is the worker service that is not working. It's requirements.txt reads
Flask~=1.1.2
google-api-core==1.22.4
google-auth==1.23.0
google-cloud-core==1.4.3
google-cloud-datastore==2.0.0
google-cloud-logging==2.0.0
google-cloud-storage==1.33.0
google-cloud-vision==2.0.0
google-crc32c==1.0.0
google-resumable-media==1.1.0
requests==2.25.0
The imports for the worker are
import os
import logging
import google.cloud.logging
import google.oauth2.id_token
from flask import Flask, render_template, request
from google.auth.transport import requests
from google.cloud import datastore
from google.cloud import vision
The full error on the Logs explorer is

I've tried rearranging the imports as I read that there could be some namespace issues but that didn't fix it
The issue seemed to be caused by the order of the components in the requirements file, similar to this issue. The solution is to explicitly include the grpcio module in the requirements.txt file, e.g. :
Flask~=1.1.2
google-api-core==1.22.4
google-auth==1.23.0
google-cloud-core==1.4.3
google-cloud-datastore==2.0.0
google-cloud-logging==2.0.0
google-cloud-storage==1.33.0
google-cloud-vision==2.0.0
google-crc32c==1.0.0
google-resumable-media==1.1.0
requests==2.25.0
grpcio==1.34.0
