 await s3
        .upload({
          Bucket: paths({ id: req.user._id, ct: fields?.ct }),
          ACL: 'public-read',
          Key: key,
          Body: body,
          ContentType: contentType,
        })
        .send((err, data) => {
          if (err) {
            return res.status(500).json('Internal Error Please try again');
          }
          if (data) {
            console.log('data', data);
            return res.status(200).json({ files: data.Location });
          }
        });
