Hey @Ruan17 and @Joao_Vitor_de_Quadro,
thanks so much for the question. I’ve responded to the same issue in another thread: Why input schema from "Call n8n Workflow Tool" was removed on 1.74.3? - #10 by Niklas_Hatje
Does that help? It might be confusing right now, since we seem to have many youtube tutorials out there right now with the old paradigm, but I hope my answer here makes sense. If not, please let me know how I can help you further.
