Я пытаюсь использовать функции Azure (HttpTrigger), чтобы читать мои электронные письма и помещать их в мою базу данных Azure. Для этого я разработал python скрипт (readEmail.py и raFunctions.py) , который работает локально в Visual Studio Code в Ubuntu. Следующий шаг, который я попробовал, - преобразовать этот скрипт в функцию Azure. Когда я пытаюсь запустить функцию Azure локально:
func host start
http://localhost:7071/api/ReadEmail?name=erik
, она возвращает следующую ошибку:
Executed 'Functions.ReadEmail' (Failed, Id=4284c861-ce2f-4755-a7e3-94e269a42bc1)

Я надеюсь, что вы можете помочь мне здесь! Я поместил сценарии python в приведенный ниже код.

После некоторой помощи я также попытался создать виртуальная среда в python, установите все необходимые модули и снова запустите забавный c хост
python -m venv .venv
source .venv/bin/activate
pip3 install azure, re, pyodbc, imaplib, email, logging
pip3 freeze > requirements.txt
func host start
Теперь я получаю сообщение об ошибке:
