Console error: 'SpatialTracking'

Unity Engine
1

Just following the instructions from the google developers website to get ARCore running in Unity leads to this console error:
Assets/GoogleARCore/SDK/InstantPreview/Scripts/InstantPreviewManager.cs(32,23): error CS0234: The type or namespace name SpatialTracking' does not exist in the namespace UnityEngine’. Are you missing an assembly reference?

I couldn’t find anything online relating to this error, and would appreciate any help.

Thanks
