NextAuth 5> with PrismaPostgres & Edge Middleware

Hi there, has anyone figured out how to get Prisma Postgres working with NextAuth 5? I am using accelerate

import { PrismaClient } from '@prisma/client'
import { withAccelerate } from '@prisma/extension-accelerate'

const globalForPrisma = global as unknown as { 
    prisma: PrismaClient
}

const prisma = globalForPrisma.prisma || new PrismaClient().$extends(withAccelerate())

if (process.env.NODE_ENV !== 'production') globalForPrisma.prisma = prisma

export default prisma

import { PrismaClient } from '@prisma/client'
import { withAccelerate } from '@prisma/extension-accelerate'

const globalForPrisma = global as unknown as { 
    prisma: PrismaClient
}

const prisma = globalForPrisma.prisma || new PrismaClient().$extends(withAccelerate())

if (process.env.NODE_ENV !== 'production') globalForPrisma.prisma = prisma

export default prisma

And got authentication working fine when I am not running edge middleware. In the (outdated) documentation using accelerate is suggested as an alternative to the adapters so I kind of figured everything would work.

But in my middleware.ts

  export { auth as middleware } from "@/auth"

  export { auth as middleware } from "@/auth"

Will cause a lot of errors

It worked fine when I was using Neon Postgres with the official adapters and I would hate to move back lol.

Things I've tried
- use canary next with nodeMiddleware flags
- move prisma instantiation into auth.js file

export const { handlers, auth, signIn, signOut } = NextAuth(() => {
  const prisma = new PrismaClient().$extends(withAccelerate())
  return ({
    adapter: PrismaAdapter(prisma),

export const { handlers, auth, signIn, signOut } = NextAuth(() => {
  const prisma = new PrismaClient().$extends(withAccelerate())
  return ({
    adapter: PrismaAdapter(prisma),

This removes the mention of auth.ts in the logs but still errors on @/lib/prisma.ts

Any tips?
