Ошибка запуска произвольного приложения Google App Engine

Question

Я пытаюсь развернуть образ докера в Google App Engine.Изображение представляет собой веб-приложение Django с веб-сервером Apache HTTP.Ниже приведен app.yaml контент

entrypoint: "apachectl start"
env: flex
runtime: custom
service: myservice

. При развертывании App Engine выдает следующую ошибку без дополнительной информации:

OperationError: Error Response: [9]
Application startup error:

Образ докера отлично работает в Kubernetes (GKE) и локальном,Я даже попытался с другой точкой входа - python /app/MyAPP/manage.py runserver 0.0.0.0:8080, но выскочила та же ошибка

Я использовал команду - gcloud app deploy --image-url gcr.io/my-12345/myapp:1 для развертывания.

Как я могу исправить эту ошибку?Что еще можно попробовать получить дополнительную информацию об ошибке?
