I have run into the same problem today. I deleted the Catalog it happened on, but now its in my Recycle bin and I can’t open that. When I looked at the Metadata for the clips I was importing I noticed there was nothing in the “Reel” field. Once I added a number to the field, I was able to add the clip to my catalog with no problems.
I am currently running CatDV 8.0 and Worker Node 3.0.1 The clips were being added through a watch action using the conversions action of Build Preview and then Publishing it in Post.
The message I get on the bottom of my catalog screen is Read only view on 0 clips from catalog ‘Recycle Bin’ (java.lang.RuntimeException: Tape name is blank)
