grpc-java: io.grpc.StatusRuntimeException: INTERNAL: No value received for unary call

io.grpc.StatusRuntimeException: INTERNAL: No value received for unary call I’m getting this Exception message from my grpc unary call while running my signed apk . I get this RunTime Exception Only when I Get a Release Version and not on debug mode please help me out I’m really getting frustrated:

here is my build.gradle (module):

}

and my build.gradle(project):

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()
        mavenCentral()
        maven { url 'https://jitpack.io' }
        maven { url 'https://maven.google.com' }

    }

    }
}

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
        maven { url 'https://jitpack.io' }
        maven { url 'https://maven.google.com' }

            dirs 'libs'
        }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

here is one of my protobuf files:

syntax = "proto3";

option java_package = "com.saphamrah";
option java_outer_classname = "AccountTypeProto";

package Amargar;

service AccountType{
  rpc GetAccountType(AccountTypeRequest) returns(AccountTypeReplyList);
}

message AccountTypeRequest{

}

message AccountTypeReply{
  int32	AccountTypeID = 1;
  string	AccountTypeName = 2;
}

message AccountTypeReplyList{
  repeated AccountTypeReply AccountTypeReplys = 1;
}

and this is how I create my unary calls:

    {
        try {
            ServerIpModel serverIpModel = new PubFunc().new NetworkUtils().getServerFromShared(context);
      
            serverIpModel.setPort("5000");

            if (serverIpModel.getServerIp().trim().equals("") || serverIpModel.getPort().trim().equals("")) {
                String message = "can't find server";
                PubFunc.Logger logger = new PubFunc().new Logger();
                logger.insertLogToDB(context, Constants.LOG_EXCEPTION(), message, NoeHesabDAO.class.getSimpleName(), activityNameForLog, "fetchNoeHesabGrpc", "");
                retrofitResponse.onFailed(Constants.HTTP_EXCEPTION(), message);
            } else {

                CompositeDisposable compositeDisposable = new CompositeDisposable();
                ManagedChannel managedChannel = GrpcChannel.channel(serverIpModel);
                AccountTypeGrpc.AccountTypeBlockingStub accountTypeBlockingStub = AccountTypeGrpc.newBlockingStub(managedChannel);
                AccountTypeProto.AccountTypeRequest accountTypeRequest = AccountTypeProto.AccountTypeRequest.newBuilder().build();
                Callable<AccountTypeProto.AccountTypeReplyList> accountTypeReplyListCallable = () -> accountTypeBlockingStub.getAccountType(accountTypeRequest);
                RxAsync.makeObservable(accountTypeReplyListCallable)
                        .map(accountTypeReplyList ->  {
                            ArrayList<NoeHesabModel> models = new ArrayList<>();
                            for (AccountTypeProto.AccountTypeReply reply : accountTypeReplyList.getAccountTypeReplysList()) {
                                NoeHesabModel model = new NoeHesabModel();

                                model.setCcNoeHesab(reply.getAccountTypeID());
                                model.setNameNoeHesab(reply.getAccountTypeName());

                            }
                            return models;
                        })
                        .subscribeOn(Schedulers.io())
                        .observeOn(AndroidSchedulers.mainThread())
                        .subscribe(new Observer<ArrayList<NoeHesabModel>>() {
                            @Override
                            public void onSubscribe(@NonNull Disposable d) {
                                compositeDisposable.add(d);
                            }

                            @Override
                            public void onNext(@NonNull ArrayList<NoeHesabModel> noeHesabModels) {
                                response.onSuccess(noeHesabModels);
                            }

                            @Override
                            public void onError(@NonNull Throwable e) {
                                response.onFailed(Constants.HTTP_EXCEPTION(), e.getMessage());
                            }

                            @Override
                            public void onComplete() {
                                if (!compositeDisposable.isDisposed()) {
                                    compositeDisposable.dispose();
                                }
                                compositeDisposable.clear();
                            }
                        });

            }
        }catch (Exception exception){
            PubFunc.Logger logger = new PubFunc().new Logger();
            logger.insertLogToDB(context, Constants.LOG_EXCEPTION(), exception.getMessage(), NoeHesabDAO.class.getSimpleName(), activityNameForLog, "fetchNoeHesabGrpc", "");

        }
    }
