CreateAnchor NullReferenceException #319

Closed rishabhaggarwal2 closed 2 years ago

rishabhaggarwal2 commented 2 years ago

I am trying to create an anchor using ASA for Hololens. First of all dll fails to attach in the editor. Then, when I build the application on the hololens, the session starts successfully and gives the percentage of room captured altough the SessionUpdated doesn't work.

Then, when trying to attach the anchor as follows:

  public async void CreateAnchor()
     {
         var localAnchor = GameObject.Instantiate(this.SpherePrefab, this.PlacementDisc.transform.position,
             this.PlacementDisc.transform.rotation);
         localAnchor.AddComponent<CloudNativeAnchor>();
         StatusText.GetComponent<TextMeshPro>().text = "anchored";
         CloudNativeAnchor cloudNativeAnchor = localAnchor.GetComponent<CloudNativeAnchor>();
         StatusText.GetComponent<TextMeshPro>().text = cloudNativeAnchor.isActiveAndEnabled ? "yayy" : "noo";
         if (cloudNativeAnchor.CloudAnchor == null)
         {
             StatusText.GetComponent<TextMeshPro>().text = "anchor was null";
             await cloudNativeAnchor.NativeToCloud();
             StatusText.GetComponent<TextMeshPro>().text = "received native to cloud";
         }  
         CloudSpatialAnchor cloudAnchor = cloudNativeAnchor.CloudAnchor;
         //cloudAnchor.AppProperties[@"model-type"] = @"frame";
         cloudAnchor.AppProperties[@"label"] = @"testing123";
         await this.cloudSession.CreateAnchorAsync(cloudAnchor);
         StatusText.GetComponent<TextMeshPro>().text = "created cloud anchor " + cloudAnchor.Identifier;
         localAnchor.GetComponent<Material>().color = Color.green;
     }

I get the following error: 

 NullReferenceException: Object reference not set to an instance of an object.

There's a similar unresolved issue here as well - https://docs.microsoft.com/en-us/answers/questions/378610/getting-started-with-azure-spatial-anchors-createa.html?childToView=624393#answer-624393

Posting here for visibility and to see if there's any resolution.

Hi @rishabhaggarwal2, thanks for reaching out! Have you had the opportunity to run the ASA Unity sample project here? Can you confirm if SessionUpdated and anchor creation work with that project? Does your project have an enabled ARAnchorManager and SpatialAnchorManager in the scene? Thanks!

Hi sorry for the delay - I wasn't able to find this thread again. i'm still working on this and was able to create and locate anchors as long as they were in the same session. Across multiple sessions, they would only be located at origin (0,0,0,)

I followed the instructions and updated my ASA to 2.11.0 instead of 2.9.0

Now, I get 

InvalidOperationException: ARAnchor still pending

Hey @rishabhaggarwal2, thanks for the update. I believe that the issue may be with the calls to CloudSpatialAnchor.GetPose(). To use that function, you will want an enabled SpatialAnchorManager in your scene and you will want to interface with SpatialAnchorManager instead of CloudSpatialAnchorSession directly. Our Unity HoloLens Tutorial shows how to do this (as does our Unity sample app). I would do a quick test and comment-out the GetPose() calls to confirm this is the case. Let us know if that works. Thanks!

Thanks @msftradford - so I updated OpenXR to 1.2.1, ASA to 2,11,0 as per the tutorial

Also changed everything to use the SpatialAnchorManager as per the tutorial.

I get the following list of errors now: 

Unable to register IMixedRealitySpatialAwarenessObserver data provider (Windows Mixed Reality Spatial Mesh Observer) because the value of concreteType is null.
This may be caused by code being stripped during linking. The link.xml file in the MixedRealityToolkit.Generated folder is used to control code preservation.
More information can be found at https://docs.unity3d.com/Manual/ManagedCodeStripping.html.

StartSessionAsync called with but no session. Creating one.

Need an enabled ARAnchorManager in the scene

InvalidOperationException: SpatialAnchorManager is improperly configured.

InvalidOperationException: ARAnchor still pending

And after all this, it doesn't end up creating an Anchor.

Here's what my gameobject with all the scripts looks like: image

@rishabhaggarwal2, thanks for the additional info. Because we cannot find the ARAnchorManager in the scene, SpatialAnchorManager does not get configured properly, and as a result the calls into SpatialAnchorManager will not work. I do see from your screenshot that ARAnchorManager and ARSessionOrigin are added to some GameObject in the inspector, so I'm not sure why we can't find the ARAnchorManager in SpatialAnchorManager.Start(). For this, we are using Unity's built-in function, Object.FindObjectOfType(), to find the ARAnchorManager in the scene and that function must be returning null for you to see that error message. Can you verify that you've also checked the capabilities and main camera settings? Is it possible that the owning GameObject is in a disabled state? Does this application have multiple scenes and is it possible that the scene hasn't finished loading? Does the tutorial work for you out-of-the-box without any changes?
