reverse gateway file not getting generated (.pb.gw.go) not getting generated no error just warning

[gautam-shipt]

Hi Team
I am trying to use the REST proxy with my Grpc service .. here is what my Proto file looks likes
syntax = "proto3";

Proto file = healthcheck.proto

package main;
option go_package = "./proto-gen;proto_gen";
import "google/api/annotations.proto";

service HealthV1 {
  rpc Check(HealthCheckRequest) returns (HealthCheckResponse) {
    option (google.api.http) = {
      get: "/api/v1/healthcheck"
    };
  };
}

message HealthCheckRequest {}

message HealthCheckResponse {}

I am using the following to generate the files

Reverse proxy Gateway generation
protoc -I. -I proto/ -I ${GOPATH}/src/github.com/grpc-ecosystem/grpc-gateway/third_party/googleapis --grpc-gateway_out=logtostderr=true,paths=source_relative:../proto-gen proto/healthcheck.proto
ERROR

WARNING: Package "github.com/golang/protobuf/protoc-gen-go/generator" is deprecated.
A future release of golang/protobuf will delete this package,
which has long been excluded from the compatibility promise.

the proto compiler is not generating the expected reverse proxy file (healthcheck.pb.gw.go)

protoc version libprotoc 3.12.3

Could you join the support channel #grpc-gateway on Gophers slack for support questions like this? This isn't a great forum for it. I'm going to close this issue.
