Microsoft.Azure.WebJobs.Script: WorkerConfig for runtime: python not found

I have Function App of Python v2 and docker based.

function_app.py:

import loggingimport timeimport azure.functions as funcfrom selenium import webdriverimport chromedriver_autoinstallerapp = func.FunctionApp()@app.schedule(schedule="0 * * * * *", arg_name="myTimer", run_on_startup=True,              use_monitor=False) def timer_trigger(myTimer: func.TimerRequest) -> None:    if myTimer.past_due:        logging.info('The timer is past due!')    chromedriver_autoinstaller.install()    browser = webdriver.Chrome()    browser.get('http://selenium.dev/')    assert "Selenium" in browser.title    time.sleep(5)    browser.quit()    logging.info('Python timer trigger function executed.')

local.settings.json:

{"IsEncrypted": false,"Values": {"AzureWebJobsStorage": "UseDevelopmentStorage=true","FUNCTIONS_WORKER_RUNTIME": "python","AzureWebJobsFeatureFlags": "EnableWorkerIndexing"  }}

requirements.txt:
