Here’s what they say about that error:
Error 13 Invalid Data: We could not find any file to process. It could be a format we don’t recognize, or a file format version we don’t support (e.g. old versions of COLLADA).
Go into the link where they offer solutions. Since the issue is on the side of Sketchfab, maybe you could contact them and hopefully hand you a better solution.
