Can someone answer me please

The access path is not found,
there is the path in html file href="/koolreport_assets/804364024/../inputs/bower_components/bootstrap-multiselect-0.9/bootstrap-multiselect.css"

i using symfony 4

i solved my problem by i have created all the folder and file expected by the path. Do you have any solutions to do that properly and do yuo know if you have another missing folder ?
