I had the same problem

export async function getQrCode(req, res) {
  try {
    console.log('inside getQrCode==>', req.client);
    const img = Buffer.from(req.client.qrcode.replace(/^data:image\/(png|jpeg|jpg);base64,/, ''), 'base64');

    res.writeHead(200, {
      'Content-Type': 'image/png',
      'Content-Length': img.length,
    });
    res.end(img);
  } catch (ex) {
    req.logger.error(ex);
    return res.status(500).json({ status: 'error', message: 'Error retrieving QRCode' });
  }
}

output

  status: 'CLOSED',
  session: 'NERDWHATS_AMERICA',
  config: { webhook: 'https://localhost:3000/', waitQrCode: true },
  qrcode: null,
