According to gRPC Error Handing <https://grpc.io/docs/guides/error/>, Richer
error model contains much more information than the standard one comes with
gRPC default. So I decided to use it for my gRPC servers for Errors.
In Java, I am able to easily use it and return Error in response as
Status status = Status.newBuilder()
.setCode(Code.INVALID_ARGUMENT.getNumber())
.setMessage("Required argument is empty.")
.addDetails(Any.pack(DebugInfo.newBuilder().addStackEntries("This
is a sample stack trace").build()))
.build();
responseObserver.onError(StatusProto.toStatusRuntimeException(status));
However, I also have gRPC servers which are written in Ruby. And I can't
find a way to raise an exception or return error status as in Java.
I did this:
debug_info = Google::Rpc::DebugInfo.new(
stack_entries: ["1", "2"] ,
)
error_status = Google::Rpc::Status.new(
code: 3,
message: "msg",
details: [Google::Protobuf::Any.pack(debug_info)]
)
# no way for me to throw exception from error_status
After i initialized a Google::Rpc::Status instance, it seems like there is
no way for me to raise an exception from error_status I created. Anyone has
any idea how I can do it in Ruby? Thanks!
