Issue with Discord OAuth2 redirect_uri component
Solution 1
I got this issue today and after debugging a while around, I found what I was doing wrong.
While I registered my application on Discord, it asked me for a redirect_uri
which we need to specify so that Discord can only allow those urls to redirect from the login page. But after fiddling a while on my project I changed the redirect url from node, which didn't match with what I already specified on Discord. That's why this issue popped up for me.
Screenshot from my discord developer dashboard (change this redirect url):
Fix: Go to Discord and update your new redirect url (as per your need). And this will fix the error on the login page that you're facing. Remember to save either by pressing enter in the field or by pressing the save-button that pops up at the bottom of the page.
Hope I could help!

I know this is resolved for a long time but i'm adding this in case someone has this issue and don't know what's happening: if you are calling the https://discord.com/api/oauth2/token
endpoint to resolve a code to a token, you have to make the redirect_uri
field the SAME as the one that generated the code with the https://discord.com/api/oauth2/authorize
endpoint, otherwise you'll get this error. It also has to be, like mentioned above, EXACTLY (querystrings don't work) the same as one of the redirects in the redirects list of your application.

I'm currently working on Discord OAuth2 client for my web application.
No matter how hard I try to set the redirect_uri to make discord not send the error, I can't get fix it, and I keep getting this message:
Invalid OAuth2 redirect_uri : You can now close this tab.
(sorry for the foreign language in the second line)
My redirect_uri is:
const redirect = encodeURIComponent("http://localhost/callback");
(the website exists on the server and works as should.)
**I tried so many combinations, including: - adding https:// instead of http:// - adding
.com
to the domain - adding a slash after the wordcallback
- using normal string instead of encodeURIComponent - generating the oauth2 redirect_uri via the Discord Developer page **The only thing that worked was totally removing the redirect_uri from the URL parameters, which made the app work, but didn't redirect to the correct place afterward;
(This is my oauth2 url):
https://discordapp.com/api/oauth2/authorize?client_id=${id}&redirect_uri=${redirect}&response_type=code&scope=identify%20guilds%20email
,when
id = client id in string type
andredirect = (above) the url
Thanks for any help.
Edit 1: setting the redirect_uri intentionally to a wrong URL, sends a JSON message saying "Badly formatted redirect_uri." (not the one visible on the screenshot!)
Edit 2: example complete url:
https://discordapp.com/oauth2/authorize?client_id=528972063096963140&redirect_uri=http%3A%2F%2Flocalhost%2Fdiscord%2Fcallback&response_type=code&scope=identify%20guilds%20email
