One file failed to sync

I synced two databases to DevonThink to Go 2.0. One file failed, however, to sync:

16.43.08: /var/folders/wp/c3xx9kgj79q9pr9d4f_8brm00000gp/T/com.devon-technologies.cloudy/2918/6360BC2D-98B4-45B6-BD39-C7D4C1383603.rtfd Failed

How can I find this find this file and what I supposed to do?
