eightshift-boilerplate: cannot find fonts while compiling

When I try npm run build i get this error

[D:\data\xampp\htdocs\wpwp2\wp-content\themes\wpwp2\skin\assets\styles\..onts\icomoon.woff]
[D:\data\xampp\htdocs\wpwp2\wp-content\themes\wpwp2\skin\assets\styles\..onts\icomoon.woff.js]
[D:\data\xampp\htdocs\wpwp2\wp-content\themes\wpwp2\skin\assets\styles\..onts\icomoon.woff.json]
[D:\data\xampp\htdocs\wpwp2\wp-content\themes\wpwp2\skin\assets\styles\..onts\icomoon.woff]

Do you have any idea what it could be(there are fonts in fonts folder)?

EDIT: I found a work around for now I simply changed the name of the fonts folder and now it works.
