Quick workaround (if you just need dev server running)

If you want to confirm it’s purely a routing-structure issue, you can run without Turbopack:

NEXT_DISABLE_TURBOPACK=1 next dev

…but you should still fix the folder layout, because the route is invalid. That error is coming from your route folder structure, not your code.

[PALLAVIKHEDLE]

In the Next.js App Router, a catch-all segment like:

app/api/auth/[...nextauth]/route.ts

must be the last path segment. You cannot put anything “under” it, like:

app/api/auth/[...nextauth]/create/route.ts

or

app/api/auth/[...nextauth]/create.ts

That’s exactly what Turbopack is complaining about: it found segments like
/api/auth/[...nextauth]/create → catch-all is not last.

I will recommend make create a sibling route

Move create out from under [...nextauth]:

app/ api/ auth/ [...nextauth]/ route.ts create/ route.ts

Now your routes are -

1. POST /api/auth/* handled by NextAuth catch-all
2. POST /api/auth/create handled by your custom route
