azure-functions-python-worker: [BUG] Azure function works locally but not when deployed

Investigative information

Please provide the following:

Timestamp: 2023-07-20T14:31:57Z
Function App name: xxxx
Function name(s) (as appropriate):
Core Tools version:C
Core Tools Version: 4.0.5198 Commit hash: N/A (64-bit) Function Runtime Version: 4.21.1.20667

Repro steps

Provide the steps required to reproduce the problem:

I developed an Azure Function iN VS code and it works locally, I can test it in Postman or in the browser.

Just a small example of one of the functions:

@app.route(route="CreatePineConeIndex")
def CreatePineConeIndex(req: func.HttpRequest) -> func.HttpResponse:
    """Create a Pinecone index.

    Args:
        req (func.HttpRequest): The HTTP request object.

    Returns:
        func.HttpResponse: The HTTP response object.
    """
    try:
        req_body = req.get_json()
        api_key = req_body.get('api_key')
        environment = req_body.get('environment')
        index_name = req_body.get('indexName')
        dimensions = req_body.get('dimensions', 1536)
        metric = req_body.get('metric', 'dotproduct')

        client = PineconeClient(api_key=api_key, environment=environment)
        client.CreateIndex(index_name, dimension=dimensions, metric=metric)

        return func.HttpResponse("Index Created", status_code=200)
    except Exception as e:
        return func.HttpResponse(f"Could not create Pinecone Index. {str(e)}", status_code=500)

I have tested the deploy from VS Code or via Azure Devops pipelines, deployment works without any errors

However the Azure Function url /api/CreatePineConeIndex shows as 404 however localhost/api/CreatePineConeIndex works

I already did this: https://learn.microsoft.com/en-us/azure/azure-functions/recover-python-functions?tabs=vscode%2Cbash&pivots=python-mode-decorators#issue-with-deployment

I added some logging and couldnt find any exception, however in the traces I can see:

No job functions found. Try making your job classes and methods public.

oh sorry, I misread 😦

I had to set the log level to debug in the host.json
