Who do I need to collaborate with to enable this? I am using n8n cloud “N8N_INSECURE_DISABLE_WEBHOOK_IFRAME_SANDBOX=true”
In short, the “problem” you’re seeing is the result of a security hardening in 1.103.x. If your workflows need to return dynamic HTML/JS, upgrading to n8n 1.104.2 or later and setting the environment variable N8N_INSECURE_DISABLE_WEBHOOK_IFRAME_SANDBOX=true will restore the old behavior. Be aware that doing so bypasses the sandbox and may expose your instance to cross‑site scripting; consider instead returning JSON/plain text or hosting your HTML separately to avoid the security trade‑off.
