I downloaded the .dwg file you sent and converted it by changing the CAD2PDF sample:
The error no filename usually means that you are passing the file into the function incorrectly. Could you reproduce the error by changing the CAD2PDF sample? If so, please send your code snippet so we can further investigate.
Your attempt at the demo WebViewer errored. The drawing you see there is just the default one. If you look at the request using the browser’s developer tools, you’ll see the same error that I posted previously.
I have also tried this using a simple console app and as expected saw the same error.
