The above suggests there may be additional change(s) required than just upgrading the required version.
I'm in contact with support as well on this as well, but unclear how to resolve. My only usage for this is to take an input excel file and convert it into a CSV for more efficient processing (Ruby is a RAM hog for large excel files).
