Using AppEngineHttpRequest 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 app_engine_routing_override is set on the queue, this value 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.

     * An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members` to a single `role`. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] \}, { "role": "roles/resourcemanager.organizationViewer", "members": [ "user:eve@example.com" ], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01T00:00:00.000Z')", \} \} ], "etag": "BwWWja0YfJA=", "version": 3 \} **YAML example:** bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time < timestamp('2020-10-01T00:00:00.000Z') - etag: BwWWja0YfJA= - version: 3 For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/).

This command is meant to be used for manual debugging. For example, RunTask can be used to retry a failed task after a fix has been made or to manually force a task to be dispatched now. The dispatched task is returned. That is, the task that is returned contains the status after the task is dispatched but before the task is received by its target. If Cloud Tasks receives a successful response from the task's target, then the task will be deleted; otherwise the task's schedule_time will be reset to the time that RunTask was called plus the retry delay specified in the queue's RetryConfig. RunTask returns NOT_FOUND when it is called on a task that has already succeeded or permanently failed.
