Description

grpc server is java, when using grPC-transcode plugin error in the background. The error is as follows:
Expected header TE: trailers, but null is received. This means some intermediate proxy may not support trailers

Environment

• APISIX version (run apisix version):3.2
• Operating system (run uname -a):
• OpenResty / Nginx version (run openresty -V or nginx -V):
• etcd version, if relevant (run curl http://127.0.0.1:9090/v1/server_info):
• APISIX Dashboard version, if relevant:
• Plugin runner version, for issues related to plugin runners:
• LuaRocks version, for installation issues (run luarocks --version):

@lxz999 , can you please check if applying this PR fixes your issue : #10851

[sheharyaar]

This is not related to #10573 , here the call is pure HTTP/2 GRPC, but the referred issue deals with HTTP/1 GRPC-Web calls.
