Core Plugins and tasks Return
Return a value for debugging purposes.
Render a templated string and return it so you can quickly inspect or reuse values during a flow.
Handy for troubleshooting (the rendered value is logged) or for generating small payloads such as headers or tokens that downstream tasks expect. Combine with template filters to control whitespace or formatting before the value is passed along.

Properties
assets
Assets this task consumes as inputs or produces as outputs, for lineage tracking and the asset graph (Enterprise Edition). A flow declaring this property on a task is rejected in the open-source edition.

IGNOREFAILWARNAsset failure behavior
Behavior applied to the task state when a declared asset fails to render, emit, or be persisted (e.g. a lock conflict): FAIL escalates it to FAILED, WARN (default) warns it if it would otherwise succeed, IGNORE leaves the state untouched.
Whether to auto-register assets referenced dynamically at runtime that are not statically declared in inputs or outputs.
The assets consumed as inputs.
