it works in http,but when i set my cluster to my grpc server i got this error
client -> envoy(wasm)-> grpc server
my wasm code is
#include <string>
#include <string_view>
#include <unordered_map>
#include "proxy_wasm_intrinsics.h"

solve by add clusters http2 option
http2_protocol_options:
max_concurrent_streams: 100
hello, i want to process grpc stream by this sdk,i deployment a wasm in my envoy,but i got error : pstream connect error or disconnect/reset before headers. reset reason: protocol error
