Hi,

I need help with crash. Please help in anyway you can. I’ve posted what I think is relevant, but please let me know if you need something more to help me.

RJsonObject.h

UCLASS(Blueprintable, BlueprintType)
class ROBOTBUILDER_API URJsonObject : public UObject
{
    GENERATED_BODY()

public:
    FJsonObject JsonObject;

    UFUNCTION(BlueprintPure, meta = (DisplayName = "ToString (JsonObject)", CompactNodeTitle = "->", BlueprintAutocast), Category = "Utilities|String")
    static FString ToString(URJsonObject* InJsonObject);
    UFUNCTION(BlueprintPure, meta = (DisplayName = "ToText (JsonObject)", CompactNodeTitle = "->", BlueprintAutocast), Category = "Utilities|String")
    static FText ToText(URJsonObject* InJsonObject);
};

RJsonObject.cpp

void URJsonObject::SetObjectArrayField(const FString& FieldName, const TArray<URJsonObject*>& Value)
{
    TArray<TSharedPtr<FJsonValue>> Array;
    for (URJsonObject* val : Value)
        Array.Add(TSharedPtr<FJsonValue>(new FJsonValueObject(TSharedPtr<FJsonObject>(&val->JsonObject))));
    JsonObject.SetArrayField(FieldName, Array);
}

FString URJsonObject::ToString(URJsonObject* InJsonObject)
{
    FString str;
    TSharedRef<FJsonObject> SharedPtr = MakeShareable(&InJsonObject->JsonObject);
    TSharedRef<TJsonWriter<>> Writer = TJsonWriterFactory<>::Create(&str);
    FJsonSerializer::Serialize(SharedPtr, Writer);
    return str;
