Describe the bug

After creating a new t3g app (my first ever) with TS, Prisma, tRPC, PostGres and creating and configuring a new discord app, after logging in via Discord oauth authorize screen, I get redirected to http://localhost:3000/api/auth/error?error=Configuration.

Stacktrace in console:

Additional information

Before, I forgot to configure the redirect in the discord app. Got an error stating that. After adding http://localhost:3000/api/auth/callback/discord as stated in the "first steps" docs, the bug as described happened.

Same here

[thathurtabit]

I'm getting this too, but should this be reported to NextAuth or maybe Discord.

This could be related: discord/discord-api-docs#7311

[Murderlon]

Were one of you able to solve it?

[nikolasstow]

I had the same issue and discovered I had put the incorrect Client Secret in my .env. I can't say this will fix your issue, but it fixed mine.

[mr-shortman]

comes from wrong credentials, i had a missing "-" character at the end of the discord secret
