Hi Cecilie,
I saw you had difficulty processing this file. I noticed that for some reason the boundaries contain elevation data (so-called "Z-dimension"), which is something that some shapefiles contain but it is not something we expect in boundary files. This made the system not able to process it. However, I have now modified the code so that the elevation data is stripped out on the server and I think this should now make it work for you when you try to process it again. Please have a look and let me know if it works.
Regards,
Paul
