updateTask changes task content, assignment, schedule, subtype, custom fields, or completion state. Use placement and follower actions for those relationships.
automations/update-asana-task.automation.ts
taskId is required. Optional fields are name, assignee (including null to unassign), assigneeStatus, completed, customFields, dueAt, dueOn, htmlNotes, notes, startAt, startOn, subtype, and account. Omitted fields remain unchanged; nullable due fields clear schedules.
Description, due, and start formats are mutually exclusive as on createTask; start fields require a compatible due field in the same input. Returns the updated AsanaTask.
