    Hi, I'm getting a similar issue which isn't fixed:
    public override bool IsSelectableBy(XRBaseInteractor interactor)
    bool IsAlreadyGrabbed = selectingInteractor && interactor.Equals(selectingInteractor);
    return base.IsSelectableBy(interactor) && IsAlreadyGrabbed;

    this scrips is inheriting from XRGrabInteractable and when I grab something its saying selectingInteractor is null.
    im using Unity version 2019.4.17 and the XR INTERACTION TOOLKIT version 0.10.0-preview.7.
    Thanks in advance.
