401 Unauthorized Request Discord API with OAuth - node.js

Question

I'm wanting to allow users of my site that use Discord to be able to "automatically" join my guild.
I have everything done except I always get a 401: Unauthorized from Discord's API using the following;
router.get("/cb", passport.authenticate("discord", { failureRedirect: "/" }), async function(req, res) {
const data = { access_token: req.user.accessToken };
axios.put(`https://discordapp.com/api/v8/guilds/${config.CyberCDN.server_id}/members/${req.user.id}`, {
headers: {
"Content-Type": "application/json",
"Authorization": `Bot ${config.CyberCDN.bot_token}`
},
body: JSON.stringify(data)
}).then((success) => {
console.log(`[DASHBOARD] ${req.user.username}#${req.user.discriminator} - Logging in...`);
console.log(success.config.data)
console.log(success.response.status)
return res.status(200).redirect("/");
}).catch((error) => {
console.log(`[DASHBOARD] ${req.user.username}#${req.user.discriminator} - Failed Logging in...`);
console.log(error.config.data.replace(config.CyberCDN.bot_token,"TOKEN"))
console.log(error.response.status)
return res.status(403).redirect("/");
});
});
I don't understand how when everything I have done is correct;
I have even asked in the Discord-API server regarding this matter with the same issue,
I did however have it working ONE TIME and now it's broke again, I have 0 clue how it broke.
My scopes are as follow "oauth_scopes": ["guilds.join"]

I found a better solution to this problem I had:
const DiscordOauth2 = require("discord-oauth2");
const discord = new DiscordOauth2();
/**
* Other required stuff for express.js goes here...
*/
router.get("/login", passport.authenticate("discord"));
router.get("/cb", passport.authenticate("discord", { failureRedirect: "/forbidden" }), async function(req, res) {
req.session.user = req.user;
res.redirect('/');
});
router.get("/support", authOnly, async function(req, res) {
discord.addMember({
accessToken: req.session.user.accessToken,
botToken: config.CyberCDN.bot_token,
guildId: config.CyberCDN.server_id,
userId: req.session.user.id,
roles: [config.CyberCDN.site_role]
}).then((r) => {
if(r) {
let date = new Date(r.joined_at);
res.status(200).json({ status: "Joined Server" });
const embed = new Embed()
.title(`New User Joined Via Site\n${r.user.username}#${r.user.discriminator}`)
.colour(16763904)
.thumbnail(`https://cdn.discordapp.com/avatars/${r.user.id}/${r.user.avatar}.webp?size=128`)
.footer(`User joined at: ${date.toLocaleDateString()}`)
.timestamp();
dhooker.send(embed);
console.log(r)
}else{
res.status(401).json({ status: "Already In There?" });
}
});
});
Basically through browsing my initial 401: Unauthorized error stumbled across a nice little OAuth2 NPM For Discord called discord-oauth2 developed by reboxer and numerous other people, which can be found here.
The helpful part was documented further down the README.md of that repo, in relation to my problem. Relation found here
I have also contributed that they add the removeMember feature also.
