The offending piece of code in nUI/Units/nUI_UnitAura.lua seem to be the following:

local function AuraTooltipEnter( self )
 
    local owner = self.hitBox and self or self:GetParent();
    
    local tooltipUpdate = function( self )
        if GameTooltip:IsOwned( owner ) then
            if owner.aura.is_weapon then GameTooltip:SetInventoryItem( owner.unit_id, owner.aura.id );
            else GameTooltip:SetUnitAura( owner.unit_id, owner.aura.id, owner.aura.filter );
            end
        end
    end
 
    if owner.aura and owner.active then
 
        self:SetID( owner.aura.id );
 
        GameTooltip:SetOwner( owner );
        tooltipUpdate( owner );
        GameTooltip:Show();
 
--      self:SetScript( "OnUpdate", tooltipUpdate );
 
    end
end

If we change the SetID line to the following it will probably stop the error going away.

if not InCombatLockdown() then
   self:SetID( owner.aura.id );
end
