I tried using the button on the script interface to fill in the name when the camera object was selected. This didn't fix the error. So I started messing with renaming the object(OB) as well as the camera(CAM) names for the camera in Blender. Eventually, I named the OB and CAM for the camera to the exact same name and I was able to export.
I wish I could track down the error better for you, but I'm at my office now and don't have access to my Octane machine at the moment. Hopefully this gives you enough information to replicate the problem.
On a side-note, I attempted to search the forums here with the keywords "camera" and "name" and the search function crapped out telling me that those terms are "too common" to be useful as search terms. Lame.

Keep up the great work, guys!
