This lib doesn't work on the IP packets. It only works on L7 layer: Http body for JSON and gRPC data frames. You can look its usage [here](https://github.com/envoyproxy/envoy/tree/master/source/extensions/filters/http/grpc_json_transcoder):

I like to see it is implemented as: 1) define a new struct struct JsonResponseTranslateOption { ::google::protobuf::util::JsonPrintOptions& json_print_options; bool stream_newline_delimted; }; replace this for the last parameter of ResponseToJsonTranslator 2)...

@lizan like to you your input on this.

What bazel version are you using?

This repo was created many years ago (4, 5 years). It is used by Cloud Endpoint [ESP](https://github.com/cloudendpoints/esp) and [Envoy](https://github.com/envoyproxy/envoy) grpc transcoding filter. Please suggest a replacement before you change them...

Yes, that is what we have been agreed upon.

Yes, definitely we are interesting to join OSS-Fuzz to fuzz test this module. We will add some fuzz tests and integrate with OSS-Fuzz.

I think IPV4 should work for all networks. It should be safe to default to IPV4Only. Or only for remote backends?

Could you check Cloud Run log to see what is logged for these 500 requests?
