Describe the issue

I have setting up Auth.js with Github Oauth and I decided to add PrismaAdapter with (mongodb) to save user account information. Without adding the adapter everything working great. But when I added the Adapter to @/auth it crash

CleanShot.2025-03-04.at.19.35.44.mp4

How to reproduce

1. Clone the project
2. Create a Github App (CLIENT_ID & CLIENT_SECRET)
3. Create a MongoBD account and get a connection string
4. Add them to the .env.local & run npx prisma generate
5. Go to src/auth/index.tscomment the adapters line
6. Launch the project clear && npm run dev don’t forget to run npm i
7. Click on the Signin with GitHub
8. After being logged signOut
9. Uncomment the adapter line
10. Refresh your browser

If you follow all these steps normally you will have the same error

Expected behavior

Normally they should not have any error. Instead I am doing something wrong but I follow the guide line per line. 😩😩😩

The @auth/prisma-adapter version ^2.8.0 is not compatible with next-auth version ^5.0.0-beta.25. To resolve this issue, revert to @auth/prisma-adapter version 2.7.2 and install it without the ^ symbol to prevent unintended updates.

Thanks I will try it

I am having the same error with a similar stack :

  npmPackages:
    @auth/prisma-adapter: ^2.8.0 => 2.8.0
    next: ^15.2.1 => 15.2.1
    next-auth: 5.0.0-beta.25 => 5.0.0-beta.25
    react: ^19.0.0 => 19.0.0

using PostgreSQL / Neon (I don't think the actual DB is related to this issue).

Thankfully, I got this error at build time, this was a bit more explicit than your logs :

> next build --experimental-build-mode compile

@activemonkeys @th3f0r3ign3r not that it fixes the current problem, in my case I was able to lock version ~2.7.4 without issue.

I almost forgot my problem is solved

Great 👍 I will try 2.7.4 to see if it will still work.

Shit like this is exactly why I hate but also love NextAuth, Auth.js, whatever we call it today.

@th3f0r3ign3r I am not sure why you consider this issue solved, I think prisma-adapter ^2.8.0 is supposed to work with ^5.0.0-beta.25. @activemonkeys and I were just providing a stopgap solution until the issue is fixed.

my bad though

[bunnyxt]

Same here, for PrismaAdapter with Postgres

Thanks for pointing this out! I was facing the same issue, and downgrading @auth/prisma-adapter to 2.7.2 worked for me as well.
