Forces a task to run now.
When this method is called, Cloud Tasks will dispatch the task, even if the task is already running, the queue has reached its xref_RateLimits or is xref_PAUSED.
This command is meant to be used for manual debugging. For example, xref_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][Task.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 xref_schedule_time will be reset to the time that xref_RunTask was called plus the retry delay specified in the queue's xref_RetryConfig.
xref_RunTask returns
NOT_FOUND][google.rpc.Code.NOT_FOUND]
when it is called on a
task that has already succeeded or permanently failed.
