      # requires [`appengine.applications.get`](https://cloud.google.com/appengine/
      # docs/admin-api/access-control) Google IAM permission for the project and the
      # following scope: `https://www.googleapis.com/auth/cloud-platform` The task
      # will be delivered to the App Engine app which belongs to the same project as
      # the queue. For more information, see [How Requests are Routed](https://cloud.
      # google.com/appengine/docs/standard/python/how-requests-are-routed) and how
      # routing is affected by [dispatch files](https://cloud.google.com/appengine/
      # docs/python/config/dispatchref). Traffic is encrypted during transport and
      # never leaves Google datacenters. Because this traffic is carried over a
      # communication mechanism internal to Google, you cannot explicitly set the
      # protocol (for example, HTTP or HTTPS). The request to the handler, however,
      # will appear to have used the HTTP protocol. The AppEngineRouting used to
      # construct the URL that the task is delivered to can be set at the queue-level
      # or task-level: * If set, app_engine_routing_override is used for all tasks in
      # the queue, no matter what the setting is for the task-level app_engine_routing.
      # The `url` that the task will be sent to is: * `url =` host `+` relative_uri
      # Tasks can be dispatched to secure app handlers, unsecure app handlers, and
      # URIs restricted with [`login: admin`](https://cloud.google.com/appengine/docs/
      # standard/python/config/appref). Because tasks are not run as any user, they
      # cannot be dispatched to URIs restricted with [`login: required`](https://cloud.
      # google.com/appengine/docs/standard/python/config/appref) Task dispatches also
      # do not follow redirects. The task attempt has succeeded if the app's request
      # handler returns an HTTP response code in the range [`200` - `299`]. The task
      # attempt has failed if the app's handler returns a non-2xx response code or
      # Cloud Tasks does not receive response before the deadline. Failed tasks will
      # be retried according to the retry configuration. `503` (Service Unavailable)
      # is considered an App Engine system error instead of an application error and
      # will cause Cloud Tasks' traffic congestion control to temporarily throttle the
      # queue's dispatches. Unlike other types of task targets, a `429` (Too Many
      # Requests) response from an app handler does not cause traffic congestion
      # control to throttle the queue.
