Problem with Prisma Adapter on edge runtime

[JacoboGanon]

I'm having an issue with the Prisma Adapter on edge runtime.

I have been investigating for a while now and I really can only pinpoint it to this.

I am using a database strategy with prisma. I have Prisma 5.12 + as indicated that is needed for edge runtime, I am using neon serverless adapter, and I have tried the queries on edge runtime and they work (before calling auth()), so interacting with the database should be possible.

The problem is in any API route that is running in edge the moment I call auth() I get the following error:

TypeError: Cannot read properties of undefined (reading 'exec')

[project]/node_modules/@prisma/client/runtime/library.js [app-edge-route] (ecmascript)
.next\server\edge\chunks\node_modules_@prisma_client_002dadf4._.js (1323:39)

My authconfig is defined as follows:

export const authConfig = {
  providers,
  adapter: PrismaAdapter(db) as Adapter,
  callbacks: {
    session: ({ session, user }) => {
      session.user.id = user.id;
      session.user.membership = user.membership;
      session.user.membershipExpiresAt = user.membershipExpiresAt;
      session.user.premiumRequests = user.premiumRequests;
      session.user.proRequests = user.proRequests;
      session.user.freeRequests = user.freeRequests;
      return session;
    },
  },
  pages: {
    signIn: "/signin",
  },
} satisfies NextAuthConfig;
