response header data as zip in node js

问题

I have tried this code to send response zip in header, but something is missing from my side. In this I am getting response as shown in screenshot

Here is my code..

const zipPath - './test.zip'; // I have a zip with 2 files inside it (password protected)
    const stat = fs.statSync(zipPath);
    res.setHeader('Content-Disposition', 'attachment; filename=devices.zip');
    res.setHeader('Content-Type', 'application/octet-stream');
    res.setHeader('Content-Length', stat.size);
     res.writeHead(200, {
       'Content-Type': 'application/octet-stream',
       'Content-Disposition': 'attachment; filename=test.zip',
       'Content-Length': stat.size
     });

    let fileStream = fs.createReadStream(zipPath);
    fileStream.pipe(res);
    res.end();
