I created interceptor like below.

// BugsnagErrorInterceptor send error to bugsnag
func BugsnagErrorInterceptor() grpc.UnaryServerInterceptor {
	return grpc.UnaryServerInterceptor(func(ctx context.Context, req interface{}, info *grpc.UnaryServerInfo, handler grpc.UnaryHandler) (interface{}, error) {
		resp, err := handler(ctx, req)
		if err != nil {
			bugsnag.Notify(err)
		}

		return resp, err
	})
}
