@maheshb15 http_filters is empty. You need to provide valid configuration.

match: { prefix: "/" }
route: { cluster: rmq_admin_service }
http_filters:

Hi Siva,

Thanks for the response,we have added http_filters as below still the same issue. http_filters:

• name: envoy.router config: {}
• name: envoy.buffer config: max_request_bytes: 100000 max_request_time: 36s

Attached config files below for reference,

@maheshb15 I see. As of now there is no mapping for http_filters other than health_check so it's a bug. Feel free to PR Envoy-Pilot if you are interested.
