Can't use negative values on int64 about grpcui HOT 3 CLOSED

@facundomedica, thanks for that. I was able to reproduce. Apparently, I totally failed when I pushed the supposed fix. Real fix incoming...

After making sure you've updated to that sha and recompiled, if it still happens, do you mind sending me a sample proto file and steps to reproduce (e.g. which field and what value to try)? Maybe there's something subtle I missed such that my earlier fix isn't correctly applied to all manner of signed ints... Having a repro case would help me find it.

@jhump sorry for the delay, here you go. It's weird, because an int32 can be set as negative but int64 can't

syntax = "proto3";
option go_package = "admin";
package admin;
import "google/protobuf/empty.proto";

service Admin {
    rpc SomeService(SomeMessage) returns (google.protobuf.Empty) {}
}
message SomeMessage {
  string user_id = 1;
  int64 amount = 2; // in this field I get the error
  int32 currency = 3; // but this one can be negative with no complains
  string message = 4;
}
