Missing :te header using grpc on a http2 ingress

[arunxls]

Hi,

I'm hitting this error

{grpc_message:"Missing :te header", grpc_status:2}

Seemingly the ingress is dropping the te trailers header as documented here. I confirm that I've set cloud.google.com/app-protocols: '{"443":"HTTP2"}' in my ingress

Any way I can get the ingress to not drop these headers?
