"Next form page" Node not working

Describe the problem/error/question

Hi guys!
I’m currently trying to bulid a workflow using n8n that is a part of the automation process at my Company. We’re uning self-hosted version of n8n. My problem is that my workflow is stopping on the “Next Form Page” node. While im trying to test-execute the workflow, it’s working correctly until it hits the “Next Form Page” then it’s just stays in a place and keeps loading and the page on a form doesn’t change to the next one. This error is appearing not only in this workflow but in all I’ve Tested. I’ve already changed the version of n8n from latest to stable and i played with changing/adding multiple variables to Docker but the Error Keeps existing. May somebody help?

Information on your n8n setup

  • n8n version: 2.3.2
  • Running n8n via: Docker and tunneling via Ngrok
  • Operating system: Windows 11

Hi @Jeremi_Nowak,

you need a “Next Form Page” node in your workflow for multi-page forms to work.

Hi! There are 4 of these nodes in this specific workflow.

Same for me!
Running on a self hosted n8n Version 1.123.7

(It never skips to the next form page)

Seems like a CSP issue due to the sandboxed iframe that is used to separate these from the n8n domain.

setting N8N_INSECURE_DISABLE_WEBHOOK_IFRAME_SANDBOX=true
Should fix the problem although its insecure. (but maybe not a big problem for internal tools?)
