Solved

the problem is caused by not starting the azurite app from vs code

• press F1 and type azurite: start
• this starts the azurite app

Note: The new azure event hub template has some new bugs if you use it 1.

from typing import List
import logging

import azure.functions as func

def main(events: List[func.EventHubEvent]):
     for event in events:
         logging.info('Python EventHub trigger processed an event: %s',
                         event.get_body().decode('utf-8'))

this produces an an event not irritable solution: use the initial template from the task instructions
