I am trying to use this library to convert HEIC files to JPG in a Codeigniter 4 controller.

I have the initial .heic file on my server with 777 permissions, and the parent folder is 777 as well.

HeicToJpg::convert('/var/www/vhosts/mydomain/httpdocs/public/assets/image1.heic')->saveAs("/var/www/vhosts/mydomain/httpdocs/public/assets/image1.jpg");

I am getting this error and i don't understand it:

CRITICAL - 2025-03-17 05:59:37 --> RuntimeException: Couldn't convert HEIC to JPG: 'sh: 1:
