Serialization JsonToYaml
Convert a JSON or JSONL file to YAML
A single JSON object becomes a plain YAML document; a JSON array or JSONL stream becomes a multi-document YAML stream with --- separators. Set jsonl to true when the input is newline-delimited JSON.

Properties
from *string
Source file URI
Pebble expression referencing an Internal Storage URI e.g. {{ outputs.mytask.uri }}.
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.
