Hi, I had the same issue and this is what I did discovered.

It is important to note that I was seeing the message two times. This is an important note.

So first, I opened the fcpxml file with a text editor, and and scrolled through the document. The fcpxml is structured with RESOURCES and CLIP tags inside a parent PROJECT. If you look inside the resources you will find a collection of ASSET tags. I began by looking for ASSET nodes that did not have a “src” attribute, and I found exactly 2. (NOTE: same number of warning messages displayed) I removed these two clips, and tried to import again.

The second import threw a new error, telling me that there where unmatched clip nodes, and the error also displayed the corresponding ID value. With this ID value I went back to my modified fcpxml and removed all the reference clips with the corresponding ID. And returned to FCP to try the import again.

It worked.

I hope that helps you.
