The module doesn't work as intended.

Problem/Motivation

The modue doesn't generate webp image of any image type, however, there is error being reported by the module.

Steps to reproduce

1) installed the module via composer
2) enabled "Webp image filter'" filter in the ckeditor5
3) I didn't have enabled "Limit HTML tags and fix broken HTML", so only "Align images" enabled and have dragged "webp fileter" under "align image".
