Auto-Args to main in Azure function App are not generated at new bindings

• Package Name: Azure func core tools
• Package Version: 2.7.2254
• Operating System: Windows
• Python Version: 3.6

Describe the bug
Have followed this URL: https://docs.microsoft.com/en-us/azure/python/tutorial-vs-code-serverless-python-07 to get the auto bindings generated. But, still after following the steps, I couldn’t get the auto generated arguments

To Reproduce
Steps to reproduce the behavior:

1. Follow the Steps as per URL above for Cosmos DB in binding with HTTPTrigger

Expected behavior
After Adding the new in binding to HTTPTrigger Azure function, expect SDK to auto-generate Args to access the data from Cosmos Graph/SQL inside function's main

Additional context
Any suggestions to get the data from grapgh DB using Gremlin API are most welcome

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @ahmedelnably, @fabiocav.

Here's a quick snippet that might help that uses the Gremlin API from Python Functions:
in init.py
`import logging
import azure.functions as func
import ast
from ..shared_code import config
from gremlin_python.driver import client, serializer

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

if req.method == "POST":
    byte_body = req.get_body()
    logging.info(thi)
    dict_body = ast.literal_eval(byte_body.decode("UTF-8"))

    f_p = dict_body['fp']
    s_p = dict_body['sp']

    try:
        x = client.Client('wss://' + config.endpoint + ':443/', 'g',
                            username='/dbs/' + config.database + '/colls/' + config.collection,
                            password=config.password,
                            message_serializer=serializer.GraphSONSerializersV2d0()
                            )
        
        query = f"g.V('{f_p}').addE('knows').to(g.V('{s_p}'))"
        logging.info("\tRunning this Grem query:\n\t{0}\n".format(query))

        callback = x.submitAsync(query)
        if callback.result() is not None:
            logging.info("\tInserted this edge: \n\t{0}\n".format(callback.result().one()))
        else:
            logging.info("Something went wrong")
    except Exception as e:
        logging.info("there was an exception: {0}".format(e))
    return func.HttpResponse(f"Hello {f_p}")

`

my function.json looks like this:
{ "scriptFile": "__init__.py", "bindings": [ { "authLevel": "anonymous", "type": "httpTrigger", "direction": "in", "name": "req", "methods": [ "get", "post" ] }, { "type": "http", "direction": "out", "name": "$return" } ] }

and then take a look here: https://github.com/Azure-Samples/azure-cosmos-db-graph-python-getting-started/blob/master/connect.py

Hope this helps!
