Azure Spatial Anchors : Inizialize the cloudSpatialAnchorSession exception

Question

Hello i have an issue to inizialize the cloudSession by code.

The idea is too attach this script to the AzureManager gameobject on the scene....for having one single session and many objects to anchor,

Does it make sense for you ?

However if the idea is fine for you, i have an error on the start session "Error on initialize the session"

Any idea? thanks Andrea

    }

    void InitializeSession()

        try {
            this.cloudSession = new CloudSpatialAnchorSession();

            this.cloudSession.Configuration.AccountId = this.AccountId;
            this.cloudSession.Configuration.AccountKey = this.AccountKey;
            this.cloudSession.Configuration.AccountDomain = this.AccountDomain;
            

            this.cloudSession.SessionUpdated += (sender, args) =>
            {
                if (args.Status.RecommendedForCreateProgress != 0)
                {
                   // TODO CREATE ANCOR FUNCTION
                }
            };    
            
        }
        catch (Exception ex) {            
            Debug.LogError("Error on initialize the session: " + ex.Message);
        }

    }        
}

The error is

Error on initialize the session: AzureSpatialAnchors assembly:<unknown assembly> type:<unknown type> member:(null)

thanks for your help Andrea

For this one, it is likely due to the Unity conflicts in the version being used with the code above using both OpenXR and XR.WSA.

For the ASA SDK, we recommend to be using OpenXR + Unity 2020/2021 LTS versions of Unity which means removal of these references:

   using UnityEngine.XR.WSA;
   using UnityEngine.XR.WSA.Input;

The sample that would recommend starting from is following if using HoloLens: https://learn.microsoft.com/en-us/azure/spatial-anchors/how-tos/setup-unity-project?tabs=xr-plugin-framework%2Cunity-2020%2Cunity-package-mixed-reality-feature-tool%2CExtraConfigurationsHoloLens
