Error when getting attachments directly from AWS public URL

[majethiyanirav]

I'm getting Error: BAD_REQUEST when trying to take PDF file directly from public URL of an AWS.

Below is the code :

let file = await request(CERT_PUBLIC_URL + data.imgPath);
where CERT_PUBLIC_URL is the url from AWS and data.imgPath is the file name from server

Below is the code to send an email

var mailOptions = {
from: from,
to: to,
subject: subject,
html: htmlToSend,
attachment: file
};

      mailgun.messages().send(mailOptions, (error, info) => {
        if (error) {
          logger.error(__filename, 'transporter.sendMail', 'No UUID', 'Error during sending an email', error);
        } else {
          logger.info(__filename, 'transporter.sendMail', 'No UUID', 'Email sent successfully.', info.message);
        }
      });

everything else is working fine.
I also tried to use
let file = await request("https://www.google.ca/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png");
which is working fine
