The queue is disabled.

A queue becomes `DISABLED` when
[queue.yaml](https://cloud.google.com/appengine/docs/python/config/queueref)
or
[queue.xml](https://cloud.google.com/appengine/docs/standard/java/config/queueref)
is uploaded which does not contain the queue. You cannot directly disable
a queue.

When a queue is disabled, tasks can still be added to a queue
but the tasks are not dispatched.

To permanently delete this queue and all of its tasks, call
[DeleteQueue][google.cloud.tasks.v2.CloudTasks.DeleteQueue].
