CloudScript with arguments calling from C++

I am absolutely new to cloud scripts, help me please with one I need. Function:

handlers.GetMultiplayerServerDetails = function (args, context) {
    var Servers = multiplayer.GetMultiplayerServerDetails({
        "BuildId": args.BuildId,
        "Region": args.Region, //Your region.
        "SessionId": args.SessionId,
    });
    return Servers; 

};

C++ call for this:

    // we are client for sure
    if (ClientAPI == nullptr)
        return false;


    PlayFab::ClientModels::FExecuteCloudScriptRequest request;
    request.FunctionName = "GetMultiplayerServerDetails";

    TSharedPtr<FJsonObject> jsonValue = MakeShared<FJsonObject>();
    jsonValue->SetStringField(TEXT("BuildId"), GarageBuildId);
    jsonValue->SetStringField(TEXT("Region"), Region);
    jsonValue->SetStringField(TEXT("SessionId"), GarageSessionId);
    request.FunctionParameter.readFromValue(jsonValue);

    bool result = ClientAPI->ExecuteCloudScript(request,
        PlayFab::UPlayFabClientAPI::FExecuteCloudScriptDelegate::CreateUObject(this, &USRCPlayfabUserClient::OnServerCloudScriptResult),
        PlayFab::FPlayFabErrorDelegate::CreateUObject(this, &USRCPlayfabUserClient::OnSharedError));
    return result;

The issue message in return result:

The problem is the data type of the transfer parameter. You can refer to the code below. You can also refer to the samples in the PlayFab Unreal SDK.

PlayFab::ClientModels::FExecuteCloudScriptRequest request;
request.FunctionName = "GetMultiplayerServerDetails";
TSharedPtr<FJsonObject> jsonValue = MakeShareable(new FJsonObject);
jsonValue->SetStringField("BuildId", " ");
jsonValue->SetStringField("Region", " ");
jsonValue->SetStringField("SessionId", " ");
auto functionParameter = PlayFab::FJsonKeeper();
functionParameter.readFromValue(MakeShareable(new FJsonValueObject(jsonValue)));
request.FunctionParameter = functionParameter;
request.GeneratePlayStreamEvent = true;
clientAPI->ExecuteCloudScript(request,
    PlayFab::UPlayFabClientAPI::FExecuteCloudScriptDelegate::CreateUObject(this, &ALoginActor::OnCloudScriptResult),
    PlayFab::FPlayFabErrorDelegate::CreateUObject(this, &ALoginActor::OnError));
