My component: `

interface SharedPDFViewerProps {
    pdfUrl: string;
    customFileName?: string;
    onDownloadClick?: () => void;
}

const SharedPDFViewer: React.FC<SharedPDFViewerProps> = ({
    pdfUrl,
    customFileName = 'document.pdf',
    onDownloadClick
}) => {
    const { viewerRef, usePDFSlickStore, PDFSlickViewer } = usePDFSlick(pdfUrl, {
        singlePageViewer: true,
        filename: customFileName,
        scaleValue: 'page-fit'
    });

const pdfSlick = usePDFSlickStore(s => s.pdfSlick);
const scale = usePDFSlickStore(s => s.scale);

return (

PDFSlick v3 uses latest pdf.js version, so make sure you have it installed. Try removing your projects node_modules and package-lock.json and then running npm install, should ensure proper versions.

in localhost is fine, but when deploy on vercel, is a crash @van100j
