res.sendFile, res.download PDF File

Question

I have currently a problem to fetch my pdf from the backend to the front-end. I'm using NodeJS.

I have all my pdf made with Puppeteer and saved on a PDF directory.

I'm trying to fetch these PDF for the front-end. (for download)

I'have tried with res.sendFile and res.download (res.sendFile(path.join(__dirname,"/path"), res.download(path.join(__dirname,"/path))

This is the response from the front-end:

{data: "%PDF-1.4↵%����↵1 0 obj↵<</Creator (Chromium)↵/Prod…e 7↵/Root 6 0 R↵/Info 1 0 R>>↵startxref↵675↵%%EOF", status: 200,...}

I can't download this files.

Code from back-end :

try { 
    res.download( path.join(__dirname, '/PDF/sofianddes.pdf'), (err) => { 
        if (err) { 
            console.log(err); 
        } 
    });
} catch (err) {}

Someone could help me ?

Thanks
