Server Error...

[mikemagruder]

I am building an Amazon clone site using Google authentication with NextAuth. I have set up my [...nextauth].js file to process the Google ID and Secret like so:
import NextAuth from "next-auth"
import GoogleProvider from "next-auth/providers/google"
export default NextAuth({
providers: [
GoogleProvider({
clientId: process.env.GOOGLE_ID,
clientSecret: process.env.GOOGLE_SECRET
}),
],
})

It works on localhost just fine, but when I deploy to Vercel, I'm getting an error. I have set up my Google ID/Secret env variables on Vercel to the same as localhost, and I have changed the NEXTAUTH_URL on Vercel to point to the Vercel hosting site, but alas, it doesn't work.

Any suggestions would be appreciated!
