Getting this error:

NullReferenceException: Object reference not set to an instance of an object UnityEngine.UI.MaskUtilities.GetStencilDepth (UnityEngine.Transform transform, UnityEngine.Transform stopAfter) (at C:/buildslave/unity/build/Extensions/guisystem/UnityEngine.UI/UI/Core/MaskUtilities.cs:73) UnityEngine.UI.MaskableGraphic.GetModifiedMaterial (UnityEngine.Material baseMaterial) (at C:/buildslave/unity/build/Extensions/guisystem/UnityEngine.UI/UI/Core/MaskableGraphic.cs:71) UnityEngine.UI.Graphic.get_materialForRendering () (at C:/buildslave/unity/build/Extensions/guisystem/UnityEngine.UI/UI/Core/Graphic.cs:233) UnityEngine.UI.Graphic.UpdateMaterial () (at C:/buildslave/unity/build/Extensions/guisystem/UnityEngine.UI/UI/Core/Graphic.cs:339) UnityEngine.UI.Graphic.Rebuild (CanvasUpdate update) (at C:/buildslave/unity/build/Extensions/guisystem/UnityEngine.UI/UI/Core/Graphic.cs:317) UnityEngine.UI.CanvasUpdateRegistry.PerformUpdate () (at C:/buildslave/unity/build/Extensions/guisystem/UnityEngine.UI/UI/Core/CanvasUpdateRegistry.cs:149) UnityEngine.UI.ScrollRect:LateUpdate()

Any ideas why?

Turns out this isn’t from scroll rect but from the mask element, not sure why I can even put the mask on something without graphics in the first place…
