Hi. Sorry, didn't see your issue before today. You get the element id that has failed, Revit has a tool to select by elementid. Then you have to check that connectors in the family are connected. The program expects 1, 2 or 3 connectors in a family. If connectors count is above 1, then it expects two of them to be connected with "Link connectors" command.
