<?php
    public function getReferer(Request $request): string
    {
        $referer = $request->header('referer', '');

        if (empty($referer)) {
            return '';
        }

        $refererHost = Url::host($referer);

It seems like $referer defined by $request->header('referer', '') on line 13 can also be of type array; however, Spatie\Referer\Helpers\Url::host() does only seem to accept string, maybe add an additional type check?

        if (empty($refererHost)) {
            return '';
        }

        if ($refererHost === $request->getHost()) {
            return '';
        }

        return $refererHost;
    }
}
