  - `newParentTaskId` string, uuid, nullable — The id of the task that will be the new parent of the selected tasks. Needed if operation is 'moveundertask'.
  - `newTaskStatusId` string, uuid, nullable — Deprecated for 'movetoproject': use TaskStatusMapping instead. The id of the new task status id to change the tasks to. Needed if operation is 'movetoproject' or 'changetaskstatus'.
  - `taskStatusMapping` TaskStatusMappingForm[], nullable — The task status mapping from old task status to new task status. Optional for operation 'movetoproject'.
    - `oldStatusId` string, uuid, required — The old task status id.
    - `newStatusId` string, uuid, required — The new task status id.
  - `newDueDate` string, date-time, nullable — The new due date for the tasks. Optional for operation 'setdates'. If not set, due and start date will be removed.
  - `newStartDate` string, date-time, nullable — The new start date for the tasks. Optional for operation 'setdates'. Only gets used when NewDueDate is set.
