Look, I just checked your JSON. Your ‘Salvar imagem1’ node is failing because you’re trying to write to /files/youtube/. Unless you explicitly mapped that volume in Docker and gave the node user (UID 1000) full permissions, n8n will bounce that request every single time. It’s a Linux permissions/mount issue, not a workflow logic error. so basically your docker-compose.yml needs a permission in the enviroment, and when you add the "- N8N_RESTRICT_FILE_ACCESS_TO=/files/youtube it should work.
thanks, i will look into that now.
