Webhhook POST trigger does not work

Hi!

The POST request trigger does not work on my n8n installation. When I try to do POST request with Postman to the following url, I get the following error “You need to enable JavaScript to run this app.”
https://n8n.domain.com/webhook-test/webhook-uid/

I have set the WEBHOOK_TUNNEL_URL to https://n8n.domain.com/

Next to that I am using Traefik and Docker for my n8n installation.

Does anybody now how to fix this?

Thanks in advance!

Did you follow this guide to set up n8n?

Hi Jan,

Thanks for quick reply. I do not know how, but your reply made me realize what the issue was. I had an external SSO service in front of n8n, therefore the GET worked in my browser but the POST did not in Postman.

Hats of this level of magical debugging! :wink:
(and sorry to waste your time)
