    Hello
    I'm following this video on YouTube at my first attempt for image tracking on Unity in AR, but for some reason I encountered two things that the video did not:

    First, at minute 8:57 he used Debug.Log(trackedImage.name); while I had to use Unity.Debug.Log(trackedImage.name); for it to work on Unity.

    Then when I finished everything else step by step I had a BuildFailedException such as the following:
    Code (CSharp):
    1. BuildFailedException: ARCore Image Library Generation: Reference library at 'Assets/ReferenceImageLibrary.asset' is missing a texture at index 1.
    2. UnityEditor.XR.ARCore.ARCorePreprocessBuild.BuildImageTrackingAssets () (at Library/PackageCache/com.unity.xr.arcore@2.1.8/Editor/ARCoreBuildProcessor.cs:286)

    5.

    6. UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)
    7.  
    Are the errors related? And how can I fix the errors? Thanks.:)
