I found this video on how to create a T3 app.
To summarize, this is what I did:
npm create t3-app@latest, use TypeScript, include all 4 features- in this case I left the DB as the default SQLite (but I tried PlanetScale too just to do exactly as the video shows)
- I tried both the default Discord, and also Google OAuth 2.0
- Pushed to Git
- I had Vercel read from the Git, set up all the env variables
On local it works perfectly, I can sign in with both Discord and Google.
But on Vercel I kept getting
Try signing in with a different account.
(with Discord after "Authorize"-ing, with Google Auth as soon as I click the "Sign in with Google" button).
I'm a bit of a noob here. What am I missing?
