Failed to import NOVO theme demo data (Error 500)

When trying to import the demo files of the NOVO theme via the OCDI plugin the import fails immediately. I already followed the instructions on the support page, increased the values in the PHP config and added the recommended lines in the functions.php of the theme. The debug file looks as follows:
