TasksTaskInfo [interface-TasksTaskInfo]

Name	Type	Description
action	string
cancellable	boolean
cancelled	boolean
description	string	Human readable text that identifies the particular request that the task is performing. For example, it might identify the search request being performed by a search task. Other kinds of tasks have different descriptions, like _reindex which has the source and the destination, or _bulk which just has the number of requests and the destination indices. Many requests will have only an empty description because more detailed information about the request is not easily available or particularly helpful in identifying the request.
headers	Record<string, string>
id	long
node	NodeId
parent_task_id	TaskId
running_time_in_nanos	DurationValue<UnitNanos>
running_time	Duration
start_time_in_millis	EpochTime<UnitMillis>
status	any	The internal status of the task, which varies from task to task. The format also varies. While the goal is to keep the status for a particular task consistent from version to version, this is not always possible because sometimes the implementation changes. Fields might be removed from the status for a particular request so any parsing you do of the status might break in minor releases.
