Exception

Unable to locate Mix file: /assets/css/test.scss.

        $manifest = $manifests[$manifestPath];

        if (! isset($manifest[$path])) {

            $exception = new Exception("Unable to locate Mix file: {$path}.");

            if (! app('config')->get('app.debug')) {

Solution

Always make sure to remove the link to the file that has been removed.

It will always try to search for the file even when it doesn't exist.
