I have had a problem when exporting a course from AT (ver. 0.10.0 / 2.4.0).

After a while the export stops, and I get this error in the Chrome console (in the AT the export progress spinner just stops):

The export zip-file is in the export folder on the AT server, and seems to be ok if I download it manually.

Somtimes something similar happens on preview (where I get an error-popup with "Oops, somthing happend"), and on publish where it "dies" silently like on export.
I both cases the course files seems to be built, but not loaded for preview og downloaded.

The console log from the AT shows no errors (but as mentioned the course files seems to be created correctly).

Has anyone had a similar experience?
