mix asset

hi,

we use metronic 8.1.7 , laravel version in my project.

after sync project with new version of metronic ( update core and assets , ... ) when build project, file mix-manifest.json create successful but not use in project. in production for apply change we should run empty cache and hard reload in browser.

for resolve this problem,
in getAsset helper function should change 'asset' function to 'mix'

but
in rtl version, files not found...
Unable to locate Mix file: /demo1/plugins/custom/fullcalendar/fullcalendar.bundle.rtl.css.


i don't know how can solve this
