Describe the issue

Currently when you try to use next-auth api routes with turbopack you get an error that x library could not be parsed.

Error: Could not parse module '[project]/node_modules/.pnpm/next@14.2.3_react-dom@18.3.1_react@18.3.1/node_modules/next/dist/server/future/route-modules/app-route/vendored/contexts/app-router-context.js'

How to reproduce

1. Use the reproduction project
2. Try login with the login button
3. See error

Expected behavior

That next-auth can be used correctly, because with webpack it works fine.

Hi @sawa-ko,
your issue seems to be related to this one: vercel/next.js#66162.
The fix will be in Next.js v14.3.0 when released

Hi @sawa-ko,
i was having this issue in version 5.0.0-beta.19. I downgraded to 5.0.0-beta.18 and it worked for me.

[sawa-ko]

@tevass I can confirm that using the version you say works fine again.

I can also confirm that 5.0.0-beta.19 is introducing issue with next@15.0.0-canary and react@19.0.0-rc.
Downgrading to 5.0.0-beta.18 is also fixing the issue with Turbo!

The same here. Thank you.

I was getting the error:
Error: Could not parse module '[project]/node_modules/next/dist/server/future/route-modules/app-route/vendored/contexts/app-router-context.js'

Thanks for posting this. I also had this error on 5.0.0-beta.19. Downgrading to 5.0.0-beta.18 fixed it 👍

Hi folks, I did some digging here! See #11551 for the solution/explanation. A fix will be out in the next release!

downgrading to 5.0.0-beta.18 worked in dev. Build still breaks. Did somebody build properly? Thanks!
