timer trigger azure function python v2 model - after deployment to azure it says "no http trigger found "

Question

I am trying to deploy an time triggered (schedule) function to azure function using the python v2 model. The function works as expected locally. I am deploying using VSCode and Azurite extension. The deployment seems to be successful, however it says that "No HTTP triggers found" (which does not make any sense because it is not an HTTP triffered function), and the function is in fact not deployed to Azure. What could be wrong here?

function_app.py

import azure.functions as func

import datetime
import logging
import requests
import json
import sys
import os

CRON_SCHEDULE = "*/10 * * * * *"

app = func.FunctionApp()
@app.function_name(name="testSendReqToApiTimeTrigger")
@app.schedule(schedule=CRON_SCHEDULE, arg_name="mytimer", run_on_startup=False, use_monitor=True)
def makeApiCall(mytimer: func.TimerRequest, context: func.Context) -> None:
    
    if mytimer.past_due:
        logging.info('The timer is past due!')

    logging.info('.context_func_dir: ' + context.function_directory)

    url = "http://worldtimeapi.org/api/timezone/Europe/Amsterdam"

    try:
        response = requests.get(url)
        print(f"request completed with status code: {response.status_code}")

    except:
        logging.error("ERROR during sending request : ")
        logging.error(str(sys.exc_info()))

The last few lines of the output of the deployment process:

...
11:24:06 AM test-timer-function: Deployment successful. deployer = ms-azuretools-vscode deploymentPath = Functions App ZipDeploy. Extract zip. Remote build.
11:24:20 AM test-timer-function: Syncing triggers...

Source Code from the given MS Doc.

import  azure.functions  as  func
import  logging
import  datetime
  
app = func.FunctionApp()

@app.function_name(name="mytimer")
@app.schedule(schedule="0 */5 * * * *", arg_name="mytimer", run_on_startup=True,
use_monitor=False)
def  test_function(mytimer: func.TimerRequest) -> None:
utc_timestamp = datetime.datetime.utcnow().replace(
tzinfo=datetime.timezone.utc).isoformat()


if  mytimer.past_due:
logging.info('The timer is past due!')
logging.info('Python timer trigger function ran at %s', utc_timestamp)

When I deploy the Python v2 Timer Triggered Azure Function, it gives the same because the actual local function project does not contain any HTTP Triggered Functions.

enter image description here

But I got the functions in the Azure Function App Portal:

enter image description here

because in the Python V2 programming model, we have to add one application setting explicitly in the Portal Function App Configuration:

"AzureWebJobsFeatureFlags": "EnableWorkerIndexing"

enter image description here

yeah i tried that too and it did work indeed just as for yourself. not sure why during the previous few deployment attempts the function was not created/propagated properly (?) I find the communication between vscode and azure portal pretty slow and unreliable at times... anyway, thanks! — average.everyman, Mar 29 '23 at 19:06
