[Python] Running an Azure Function locally results in a worker error

I created a local Azure function project on Windows using the following CLI commands from the Azure documentation:

func init --python

func new --name HttpExample --template "HTTP trigger" --authlevel "anonymous"



Running these commands results in the following Azure function being created:

import azure.functions as func
import datetime
import json
import logging

app = func.FunctionApp()

@app.route(route="HttpExample", auth_level=func.AuthLevel.anonymous)
def HttpExample(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:
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
)


The requirements.txt created by the Azure Function Core Tools includes only the azure-functions library.

After starting the function with the func start command, the worker exits with the following error:

Found Python version 3.12.0 (py).

How can I fix this?

What I tried:

• I checked that the core Azure Functions Core Tools were working properly
• I updated pip and recreated the python venv
• I reinstalled Azure Function Core Tools
• I checked that npm and node.js were properly installed and functioning
• I re-did all steps from the documentation in a different directory to make sure I didn't miss anything
