Microsoft Graph API outlook send attachments - node.js

Question

How do you send attachments with the Microsoft graph outlook API? I understand everything for sending attachments up until the content bytes. The files that I need to send are a word document a pdf and a jpeg Is it asking me to turn the file into bytes, if so how would I do that? I am using node.js and I have the following code:
exports.send_mail = async function(req, res, next) {
let parms = { title: 'Inbox', active: { inbox: true } };
const accessToken = await authHelper.getAccessToken(req.cookies, res);
const userName = req.cookies.graph_user_name;
if (accessToken && userName) {
parms.user = userName;
// Initialize Graph client
const client = graph.Client.init({
authProvider: (done) => {
done(null, accessToken);
}
});
//read test.html
//so you have to wait for the file to read then send it
message = fs.readFileSync('views/test.html', 'utf8');
console.log(rawImage.data.toString('utf8'))
try {
mailMess ={
message:{
subject: 'This is a test',
body:{
ContentType: 'HTML',
Content: message
},
ToRecipients:[
{
EmailAddress:{
Address: 'name#email.com'
}
}
],
"attachments": [
{
"#odata.type": "#microsoft.graph.fileAttachment",
"name": "attachment.jpeg",
"contentBytes": "not sure what to put here"
}
]
}
}
//sendmail
const result = await client
.api('/me/sendmail')
.version('v1.0')
.post(mailMess);
res.status('202')
parms.messages = result.value;
res.redirect('/');
} catch (err) {
parms.message = 'Error retrieving messages';
parms.error = { status: `${err.code}: ${err.message}` };
parms.debug = JSON.stringify(err.body, null, 2);
res.render('error', parms);
}
} else {
// Redirect to home
res.redirect('/');
}
}

I found out that param takes the file encoded as base64
