Environment Info

Payload: 3.0.0-beta.109
Node.js: 20.13.1
Next.js: 15.0.0-canary.173

Describe the Bug

After upgrading to the latest Next.js canary version, I get an error:

src/app/(payload)/api/[...slug]/route.ts
Type error: Route "src/app/(payload)/api/[...slug]/route.ts" has an invalid "GET" export:
  Type "{ params: { slug: string[]; }; }" is not a valid type for the function's second argument.

As mentioned in this Next.js PR:

params and searchParams are now promises

I fixed the same error when it comes to my Next.js code, but as advised, the Payload files are generated automatically and I should not modify them.

Reproduction Steps

• Create a Payload 3 (beta 109) and Next.js 15 (171) project.
• Run pnpm / npm run build
