Help with max_request_headers_kb on 1.2.x

Config
1

Hi all,

I’m trying to configure envoy max_request_headers_kb on istio 1.2.10 (It’s a production server, so no I cannot upgrade to more recent version :wink: )

I’ve tried with:

---
apiVersion: networking.istio.io/v1alpha3
kind: EnvoyFilter
metadata:
  name: max-request-headers-kb
  namespace: mynamespace
spec:
  workloadLabels:
    app: myapplication
  filters:
    - listenerMatch:
        portNumber: 8080
        listenerProtocol: HTTP  
      insertPosition: 
        index: BEFORE
        relativeTo: envoy.http_connection_manager
      filterType: HTTP
      filterName: "max_request_headers_kb"
      filterConfig: 
        value: 90

but envoy is reporting
Error adding/updating listener(s) 0.0.0.0_8080: Didn't find a registered implementation for name: 'envoy.http_connection_manager'"

Can anyone suggest the proper way to configure max_request_headers_kb envoy parameter on given version (envoy version seems to be 1.11.0-dev)? Thanks in advance!
