Error message exporting from Blender 2.8

I am getting the following error message when exporting from Blender 2.8


Additionally, the documentation link from Preferences is throwing 404 error

This is new Blender scene and no objects are from previous versions. The camera is tracking an empty (CamPivot).

This was fixed already today. Download beta 7. Docs are not done by me.
