Issue with redirect-url with Vercel

I’m trying to set up a Preview deployment with Vercel. I have set my Preview specific env variables for Auth0 and I have set a specific preview URL as well. Now, all of my preview deployments go to https://preview.myapp.com. The problem is, when I click “Login”, the redirect-url is: https://{app-name}-hktimzl6y-{project-name}.vercel.app/api/auth/callback - so it’s failing to login
