Unclearable "UnassignedReferenceException: The variable canvasRectTransform of InteractableUIMirror has not been assigned." errors are spammed in the Console when creating Quad Layer GameObject after creating Quad Layer UI Panel

Package: XR Composition Layers

Open

2.4.X

Steps to reproduce:
1. Create new Unity project using Universal 3D Template
2. Open Package Manager
3. Install “XR Composition Layers” package
4. In Hierarchy right-click and create Quad Layer UI Panel GameObject (XR > Composition Layers > Quad Layer UI Panel)
5. In “Install XR Interaction Toolkit” pop-up press “Yes”
6. In Hierarchy right-click and create Quad Layer GameObject
7. Observe the Console window

Actual results: “UnassignedReferenceException: The variable canvasRectTransform of InteractableUIMirror has not been assigned.” Errors are continuously spammed in the Console window

Expected results: No errors are spammed in the Console window

Reproducible with versions: 2.4.0 (6000.6.0a7)

Can’t test with versions: 6000.5.0b12, 6000.6.0a1 (NullReferenceException errors are spammed in the Console after creating Quad Layer UI Panel GO)

Tested on (OS): Windows 11, macOS Tahoe 26.4.1

UnassignedReferenceException: The variable canvasRectTransform of InteractableUIMirror has not been assigned.
You probably need to assign the canvasRectTransform variable of the InteractableUIMirror script in the inspector.
