Invalid HTTP header field

[rnd4222]

Hi,

I'm trying to use warp-grpc as a control plane server for envoy, which uses nghttp2 for a http2/grpc client.

And I'm getting an error (originating from nghttp2):

invalid frame: Invalid HTTP header field was received on stream 1

Here is response dump from envoy logs:

':status', '200'
'date', 'Sat, 04 Apr 2020 21:39:41 GMT'
'server', 'Warp/3.3.9'
'content-type', 'application/grpc+proto'
'grpc-encoding', 'identity'
'trailer', 'grpc-status'
'trailer', 'grpc-message'

I'm still investigating - but can you suggest what can be wrong with it? Thanks.

Here is how it looks on a server side (using warp request logger):

[request] Request {requestMethod = "POST", httpVersion = HTTP/2.0, rawPathInfo = "/envoy.service.discovery.v3.AggregatedDiscoveryService/StreamAggregatedResources", rawQueryString = "", requestHeaders = [("Host","ads"),("TE","trailers"),("Content-Type","application/grpc"),("x-envoy-internal","true"),("x-forwarded-for","192.168.0.1")], isSecure = True, remoteHost = 127.0.0.1:35920, pathInfo = ["envoy.service.discovery.v3.AggregatedDiscoveryService","StreamAggregatedResources"], queryString = [], requestBody = <IO ByteString>, vault = <Vault>, requestBodyLength = ChunkedBody, requestHeaderHost = Just "ads", requestHeaderRange = Nothing} status=Status {statusCode = 200, statusMessage = "OK"}
