Nodemailer crashes when sending bigger image in base64

I want to embed a qrcode into email. This is the code which I am using right now to add a attachment:

mailOptions.attachments = [{
    filename: 'image.png',
    content: url.split("base64,")[1],
    encoding: 'base64'
}];

It works if the url is equal to:

"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAGAAAABgAQMAAADYVuV7AAAABlBMVEUAAAAAAAClZ7nPAAAAAXRSTlMAQObYZgAAAB9JREFUeAFjgIJRwP+BZM4oh/8/GHygIYd8h45yRgEAaHBnmaA4EHkAAAAASUVORK5CYII=";

However, when I change it to qrcode:

data:image/png;base64,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

the code is crushing and gives me the following error:

Error: Connection closed
at SMTPConnection.<anonymous> (...\node_modules\nodemailer-smtp-transport\lib\smtp-transport.js:113:29)
...

I believe it is caused by the fact that the qrcode is bigger, then the first image, however, it is still relatively small. I tried many ways but nothing gives me positive results. Any ideas on how to fix that?

If you are accessing images from physical location than use this code

var mailOptions = {
attachments: [{'filename': 'image.png','path': '\pathtoimagefile\image.png'}]

if you are generating qrcode from code than 

    var qr_png = qr.imageSync('string', {
                    type: 'png'
                })
    var mailOptions = {
    attachments: [{'filename': 'image.png', 'content': qr_png}]

This code works for me

Note: I am using 'qr-image' for converting text to qr code.
