      # Google IAM permission for the project
      # and the following scope:

      # 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_url
      # 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.
