Are you using the Dart gRPC library? If so, I think your issue belongs in https://github.com/grpc/grpc-dart.

[u007]

yes, but when i use the dart library to retrieve from dart server, it works properly. but when on nodejs, the int32 behave that way. double works properly thou... do i have to file this bug in dart grpc?

[murgatroid99]

I misunderstood your initial issue. It looks like you're talking about a Protobuf problem. What protobuf library are you using with your Node.js clients?

[u007]

google-protobuf: "3.12.2"

[murgatroid99]

I am guessing that that means that you generated the code using the grpc-tools package. Can you try updating to the latest version of that library and re-generating the code. There was a relatively recent release with a newer version of the code generator.

If that doesn't help, google-protobuf and protoc are maintained in this repository: https://github.com/protocolbuffers/protobuf. That is probably the best place to file an issue about this. When you do I suggest sharing the contents of the .proto files, or at least the message type(s) that you are having problems with, so that they can see the problem more specifically.

iam using grpc-tools 1.9.0, ok i will try to raise ticket there.
