Include file '/home/cmyk/printer_data/config/cx_printer.cfg' does not exist

I am trying to get mainsail working with my Creality Ender V3 SE.
I added the printer.cfg but after that it complains about another file and there is no information I could find anywhere about this.

Mainsail cannot show you any more informations about this file, because this is part of your uploaded printer.cfg and you should know where this file is...

pls dont just copy any file, without reading them or know what this file do...
