log

Write a templated message to the run log and pass data through

Appends a resolved message to the run log (CLI stderr / desktop Logs). Passes the previous output through, adding a logged field when the input is a plain object.

message is templated ({{input.*}} or {{nodes.id…}}). How flows work.

Log line; wire continues. Multiple outgoing edges (fan-out) share the same output.
