[FIXED] Java11 appengine standard incorrect app.yaml handler

Issue

I have spring boot application running on app engine standard, I want to enforce https for all urls.

this is my app.yaml file:

runtime: java11

instance_class: F2

automatic_scaling:
  max_instances: 1

env_variables:
  SPRING_PROFILES_ACTIVE: "prod"

handlers:
- url: /.*
  secure: always

But during deployment I get this error:

it says Unknown url handler type. but it seems ok to me

Solution

In the end I used this handler and it now works:

handlers:
- url: .*
  secure: always
  script: auto
