Multiple Area targets: Failed to create AreaTargetObserver:DATABASE_LOAD_ERROR

By yuaiki on Thu, 03/10/2022 - 02:55

Hi,

https://library.vuforia.com/develop-area-targets/multiple-area-targets

I followed this article to use 2 area targets in my project, though, whenever I run it as simulator mode, it gives an error below. 

I am using the Unity version2020.3.30f1 and VuforiaEngine 10.5.5.

Actually when I deactivate either of areaTargets to make it single areaTarget, it works well. So probably there is something preventing it to have 2 active area targets.

What could be the cause of it??

 

```

Exception in callback: Failed to create AreaTargetObserver: DATABASE_LOAD_ERROR.

UnityEngine.Debug:LogErrorFormat (string,object[])

Vuforia.Utility.ExtensionMethods.DelegateHelper:InvokeDelegate (System.Delegate,object[])

Vuforia.Utility.ExtensionMethods.DelegateHelper:InvokeWithExceptionHandling (System.Action) Vuforia.Internal.Core.Engine:OnStart () Vuforia.Internal.Core.Engine:Start (System.Action) Vuforia.Internal.Core.Engine:Start () Vuforia.VuforiaBehaviour:VuforiaInitialized (Vuforia.VuforiaInitError) System.Delegate:DynamicInvoke (object[]) Vuforia.Utility.ExtensionMethods.DelegateHelper:InvokeDelegate (System.Delegate,object[]) Vuforia.Utility.ExtensionMethods.DelegateHelper:InvokeWithExceptionHandling<Vuforia.VuforiaInitError> (System.Action`1<Vuforia.VuforiaInitError>,Vuforia.VuforiaInitError) Vuforia.Internal.Core.Engine:add_OnVuforiaInitialized (System.Action`1<Vuforia.VuforiaInitError>) Vuforia.VuforiaBehaviour:Awake ()

```

 

Hi,

I may find the solution.

When I test with a new databse, it has worked.

So probably it was caused by the old database which was scanned by older version of AreaTargetCreator app.

 

Thanks.
