Azure Function in Python not able to use pymongo

I have a MongoDB running in a AKS and a load balancer created for exposing it outside AKS cluster. I also have set the bindIP in mongod.conf using below command

sed "s,\\(^[[:blank:]]*bindIp:\\) .*,\\1 0.0.0.0," /etc/mongod.conf
mongod --config C:\mongodb\conf\mongodb.conf

I have an Azure function written in python to connect to the db.

I am new to python and just trying out the basic code to connect to the mongodb.

import logging

import azure.functions as func
import pymongo


def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    name = req.params.get('name')
    if not name:
        try:
            req_body = req.get_json()
        except ValueError:
            pass
        else:
            name = req_body.get('name')

    #if name:
    elif name:
        uri = "mongodb://User:[email protected]:27017/testdb"
        client = pymongo.MongoClient(uri)

        db = client.test
        return func.HttpResponse(f"Hello, {name}. This HTTP triggered function executed successfully.")
    else:
        return func.HttpResponse(
             "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.",
             status_code=200
        )

When I am trying to run the code I am getting the below error, any help is appreciated.

Result: Failure Exception: ModuleNotFoundError: No module named 'pymongo'.

There are several reasons the error might be related to as described here:

  1. How do you deploy (VSCode, Azure Devops) is the requirements.txt part of the code deployed?
  2. is the pymongo compatible with python version of your azure function? it is compatible according to this https://pypi.org/project/pymongo/3.9.0/.
  3. the function has WEBSITE_RUN_FROM_PACKAGE set to 1?

you need to troubleshoot and check the guide in here: https://aka.ms/functions-modulenotfound
