Hi Vishal,

hope you're doing well.

Correct me if I'm wrong here but his configuration is related to
NGINX Ingress Controller from Kubernetes project, right?
If so, I'd recommend to contact to that project.

In case of NGINX OSS or NGINX Plus Ingress Controller from NGINX Inc.
please visit the following page to get contact information,
https://github.com/nginxinc/kubernetes-ingress/

Thank you.
