Describe the bug

After #14947, the ecommerce template fails pnpm build with a TypeScript error in src/utilities/generatePreviewPath.ts:

./src/utilities/generatePreviewPath.ts:1:37
Type error: Cannot find module '@/app/(frontend)/next/preview/route' or its corresponding type declarations.

The utility imports PreviewSearchParams from @/app/(frontend)/next/preview/route, but the route actually lives at src/app/(app)/next/preview/route.ts. The route group was renamed but the import wasn't updated.

To Reproduce

1. Scaffold from the e-commerce template
2. Run pnpm build.
3. TypeScript check fails with the error above.

Expected behaviour

Template builds cleanly out of the box.

Suggested fix

In templates/ecommerce/src/utilities/generatePreviewPath.ts line 1, change:

import { PreviewSearchParams } from '@/app/(frontend)/next/preview/route'

to:

import { PreviewSearchParams } from '@/app/(app)/next/preview/route'

Environment

• Payload: 3.84.0
• Next.js: 16.2.3
• Node: 20
• Template: ecommerce
