My zip folder is structured as the following screenshot. (Did I mess up the formatting by any chance?)
When I try to upload it, the right bottom popup status is stuck at “Uploading file at 64 B/s… 100%”
Using the Network section of Chrome Developer Tools shows that the import_zip request fails with the response “ErrBadZIPStructure”
NB: The output files are empty, not sure if that might be causing it.
