I am currently processing a bunch of DWG files where the majority of them are working fine. There are a handful that result in the above question title as the error message no matter what transformer I use, how few or many CAD layers I involve, whether it is a new blank workspace or not. The error even shows up when I select 'OK' in the 'Add Reader' window and before I even select what layers to load in the following individual feature types window.
Any ideas on why this might be happening for some dwgs and not others?
TIA
