Panel Button HTTP REST POST CORS error


I am getting this error trying to to an HTTP REST POST request from the Button Panel:

Using curl from my machine it works with no problem. This URL (The URL to call) is provided by an Kubernetes Ingress resource.

Could you help me to solve this CORS error?

Thanks in advance.

That application, which you are trying to call must allow request in the preflight request. So that’s not a Grafana issue.
