json

Pass through or subset the previous node output with optional JMESPath

Selects JSON for the next step — either the whole previous output or a JMESPath subset. Useful as a display/debug step or to narrow data before assert / transform.

For run-panel / --input data, use {{input.*}} (not this node’s root). Expressions are JMESPath on previous — body, not previous.body or input.field (How flows work).

Passthrough or JMESPath subset. Multiple outgoing edges (fan-out) share the same output.
