Function

This API is used by an application server to retry a batch task. Currently, task_type can only be set to firmwareUpgrade or softwareUpgrade. If the task specified by task_id is successful, stopped, being stopped, waiting, or being initialized, this API cannot be called. If the request body is {}, all subtasks in the Fail, FailWaitRetry, and Stopped statuses will be re-executed after this API is called.
