Create a task execution record

Error information when task execution fails. Only set when status is 'failed'. Contains error message, type, and stack trace. Structure: {'message': str, 'type': str, 'traceback': str} Used for debugging and error reporting.

ID of the parent flow execution containing this task. Used to determine organization_id and maintain execution hierarchy.

Input parameters provided to the task executor. Schema varies by task type. Can be dict, list, or primitive types. NULL if task has no input parameters.

Output data produced by the task executor upon completion. Only set when status is 'completed'. NULL for queued/running/failed states. Available to downstream tasks via {{task_name.output}} syntax.

Current execution status of the task. Valid values: 'queued', 'running', 'completed', 'failed', 'cancelled'. Server validates against ExecutionStatus enum. Status transitions are: queued → running → (completed|failed|cancelled).

Zero-based execution index for this task. Increments for each execution of the same task (retries, loops). Combines with flow_execution_id and task_name to form unique identifier.

Name of the task as defined in the flow definition YAML. Must match a task name in the flow's task list. Case-sensitive identifier used for task lookups.

ID of the parent flow execution containing this task. Establishes the execution hierarchy and determines organization scope. All tasks in a flow execution share the same flow_execution_id.

Unique identifier for this task execution. Auto-generated UUID assigned at creation time. Used for direct resource access via GET /task-executions/{id}.

Input parameters provided to the task executor. Schema varies by task type; can be object, array, or primitive. NULL if task accepts no input parameters. Resolved from flow definition and upstream task outputs.

Identifier of the actor who last modified this task execution. Tracks manual interventions vs automated updates for auditing. Defaults to 'system' for worker-initiated changes.

Values:

• 'system': System-automated changes (workers, background jobs)
• User ID: UUID string of the user who made the change (e.g., '123e4567-e89b-12d3-a456-426614174000')
• Integration type: For service accounts/integrations (e.g., 'integration', 'service-account')

ID of the organization owning this task execution. Inherited from parent flow execution for tenant isolation. Used for Row-Level Security (RLS) filtering and authorization. All task executions are scoped to a single organization.

Zero-based execution index tracking task attempts. 0 = first execution, 1 = first retry, 2 = second retry, etc. Increments for each retry or loop iteration of the same task. Combines with flow_execution_id and task_name to form unique composite key.

Name of the task as defined in the flow definition YAML. Case-sensitive identifier matching flow configuration. Used to reference task in flow logic and dependency graphs.
