Method POST not allowed when deploy rasa-x with nginx ingress controller enabled

[Deprecated] Rasa X Community Edition
1

Hi. I deployed rasa-x to gke with helm. I disabled nginx and enabled ingress nginx for rasa-x.

After that I cannot use /webhook.

If I port forward rasax production, I can post /webhooks/rest/webhook to get response.

But if I call http://ingressaddress/webhooks/rest/webhook, I got error 405: Method Not Allowed.

I can login to rasa-x, and post method works fine for my other services. How should I fix this?

Thanks!
