How to reproduce

Expected behavior

shouldn’t throw any type errors with a normal prisma client (no extension)

try this

import type { Adapter } from 'next-auth/adapters';
...
adapter: TypeORMAdapter(connection) as Adapter,

P.S. No matter which adapter you have, it should help with every adapters

I got the feedback that Type 'Adapter' is not generic.

export const handle = SvelteKitAuth({
	adapter: PrismaAdapter(prisma) as Adapter,
	providers: [
		...
	]
});

I can confirm that I’m still having type errors with the latest versions:

Using this Schema.

    "@auth/prisma-adapter": "^1.0.1",
    "next-auth": "^4.23.1",

export const authOptions: NextAuthOptions = {
  adapter: PrismaAdapter(db),
// ^~~~~   TypeError           
  providers: [getEmailProvider()],
//...
}

No errors when using latest @next-auth/prisma-adapter

@Puetz as @next-auth is becoming @auth that’s probably not the right way.

@OrJDev please re-open as the problem still persists, even with latest @auth/prisma-adapter.

nickjanssen on Aug 12, 2023

use @auth/prisma-adapter to solve this issue

OrJDev on Aug 5, 2023

Had this same issue in a SvelteKit project. Type assertion worked for me and didn’t get errors on runtime, should be a good temporary solution.

import SvelteKitAuth from '@auth/sveltekit'; // Using SvelteKit as an example
import type { Adapter } from '@auth/core/adapters';

export const handle = SvelteKitAuth({
  adapter: PrismaAdapter(prismaClient) as Adapter<boolean>,
  providers: [
    // ...
  ]
});

Why was this issue closed? I just set up my Next JS project with

"@auth/prisma-adapter": "^1.0.1"
"next-auth": "^4.22.5"

and I’m having the exact same problems as everyone mentioned.
So I installed "@next-auth/prisma-adapter": "^1.0.7" which works for me.

Please fix either your documentation about the prisma adapter or fix the type error for the newest versions of next-auth and @auth/prisma-adapter.

Puetz on Aug 11, 2023

Not sure if it can help someone, but I solved it by using:

import { Adapter } from 'next-auth/adapters';
import { PrismaAdapter } from '@auth/prisma-adapter';

const nextAuthOptions = {
  ...,
  adapter: <Adapter>PrismaAdapter(prismaClient),
  ...,

With versions:

...
"next-auth": "^4.24.5",
"@auth/prisma-adapter": "^1.3.3",
...

This fixed my problem also. I think they should update a documentation a bit. Maybe we can help them? Open a pr? Because right now i feel a bit lost.

Looks like the module @next-auth/adapters is no longer existing, so the only solution is using @next-auth/prisma-adapter. I would suggest fixing the docs, or fixing the package

LeonardoTrapani on Jul 30, 2023

Which Schema should I use with “@next-auth/prisma-adapter”? The one shown in the v3 version or the one shown for “@auth/prisma-adapter”?

next-auth v3: https://next-auth.js.org/v3/adapters/prisma auth: https://authjs.dev/reference/adapter/prisma

@ShriPunta this is more about the Adapter and typescript types I think. Adding the Adapter worked for prisma as well

import type { Adapter } from 'next-auth/adapters';

...

export const authConfig: NextAuthOptions = {
	adapter: PrismaAdapter(db) as Adapter,

...

TypeORMAdapter is a sibling or alternative to PrismaAdapter, both are one of the many adapters for next-auth

Hi @YuraD can you please explain with more context. I am not able to understand what is connection here? Also what do you mean by TypeORMAdapter? where can I import this function?

I am errors in the Prisma adapter index.ts

One of the errors:

Type '(email: string) => Prisma__UserClient<User | null, null>' is not assignable to type '(email: string) => Awaitable<AdapterUser | null>'.
  Type 'Prisma__UserClient<User | null, null>' is not assignable to type 'Awaitable<AdapterUser | null>'.
