That happens when trying to import a Mixamo animation for a skeleton asset that has already been retargeted using the "Mixamo Animation Retargeting" plugin for Unreal Engine. This error occurs due to the addition of a Root bone to the skeleton hierarchy that is required to support Root Motion animations. The animations from Mixamo don't have a track for this bone, so the import fails.
