My RealtimeModel is not created

I have added a new script to my gameObject that implements a RealtimeModel. But when I play the game the this.model variable is null How the script is setup:

public class NCEasyDictionarySync : RealtimeComponent<NCEasyDictionaryModel> 
{
    public NCEasyDictionaryModel Model => this.model;
}

[RealtimeModel]
public partial class NCEasyDictionaryModel {
  [RealtimeProperty(1, true, true)]
  private bool _v1;
  [RealtimeProperty(2, true, true)]
  private RealtimeDictionary<ValuesModel> _valuesDict;
}

[RealtimeModel]
public partial class ValuesModel
{
    [RealtimeProperty(1, true, true)] 
    private int _valueINT;
    [RealtimeProperty(2, true, true)]
    private Vector3 _valueVector3;
    [RealtimeProperty(3, true, true)]
    private string _valueString;
}

public class NCEasyDictionarySync : RealtimeComponent<NCEasyDictionaryModel> 
{
    public NCEasyDictionaryModel Model => this.model;
}

[RealtimeModel]
public partial class NCEasyDictionaryModel {
  [RealtimeProperty(1, true, true)]
  private bool _v1;
  [RealtimeProperty(2, true, true)]
  private RealtimeDictionary<ValuesModel> _valuesDict;
}

[RealtimeModel]
public partial class ValuesModel
{
    [RealtimeProperty(1, true, true)] 
    private int _valueINT;
    [RealtimeProperty(2, true, true)]
    private Vector3 _valueVector3;
    [RealtimeProperty(3, true, true)]
    private string _valueString;
}

It's important to note that I have used this script for ages and it worked so far. Now there's one game object breaking things. It's a prefab btw. When I enter play mode the RealtimeModel on the RealtimeView is not present so I tried to click Rebuild Realtime View but it didn't help

Hi @gubebra. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- I can see a few potential issues with your RealtimeModel setup. Let me help you troubleshoot why your model is null. First, I notice that your NCEasyDictionaryModel class is missing the [RealtimeModel] attribute, which is required for Normcore to recognize it as a model class:

[RealtimeModel]
public partial class NCEasyDictionaryModel {
  [RealtimeProperty(1, true, true)]
  private bool _v1;
  [RealtimeProperty(3, true, true)]
  private RealtimeDictionary<ValuesModel> _valuesDict;
}

[RealtimeModel]
public partial class NCEasyDictionaryModel {
  [RealtimeProperty(1, true, true)]
  private bool _v1;
  [RealtimeProperty(3, true, true)]
  private RealtimeDictionary<ValuesModel> _valuesDict;
}

Also, there's a gap in your property IDs (1, 3) - while this isn't causing your issue, it's generally good practice to use sequential IDs. Here are some common reasons why your model might be null: 1. RealtimeComponent not registered with RealtimeView: Check if your component appears in the RealtimeView's component list in the inspector. If not, try removing and re-adding the component to automatically register it with the RealtimeView Common Questions. 2. Instantiation method: If you're instantiating the prefab, make sure you're using Realtime.Instantiate() instead of Unity's GameObject.Instantiate(). Using the wrong instantiation method is a common cause of null models Common Questions. 3. Timing issues: If you're checking the model in Awake() or Start(), it might not be initialized yet. Instead, override OnRealtimeModelReplaced() to handle initialization when the model is ready RealtimeComponent. 4. Corrupt prefab: The prefab might be corrupt, causing the RealtimeComponent not to appear in the component list on the RealtimeView. 5. Unity version update: If you recently updated Unity, there might be compatibility issues with your current Normcore version. Make sure you're using the latest Normcore version compatible with your Unity version. Since you mentioned this script worked before and only one game object is causing issues, I'd recommend: 1. Check if the RealtimeView on this specific prefab has your component listed 2. Try creating a new prefab with the same components to see if that resolves the issue 3. Ensure you're waiting for the model to be initialized by implementing OnRealtimeModelReplaced() If none of these solutions work, you might need to check for any compilation errors in your project, as these can prevent Normcore from properly initializing models. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

I think it's the issue #3 (Timing issues) thanks. And yeah I added [RealtimeModel], is just that I forgot to write it here
