next/headers call prevent sitemap generation

[bastienrobert]

Describe the bug When headers() (imported from next/headers) is called in a layout.js or in a page.js file, next-sitemap doesn't generate.

To Reproduce Link to the repro: https://github.com/bastienrobert/next-sitemap-generation-with-headers-repro

Steps to reproduce the behavior:

• create a new project with pnpm create next-app
• install next sitemap
• create a basic next-sitemap.config.js file
• add postbuild script
• add headers() call (from next/headers) in layout.js
• run pnpm build
• run pnpm postbuild

sitemap is empty

• remove headers() in layout.js
• run pnpm build
• run pnpm postbuild

sitemap-0.xml is generated

Expected behavior sitemap-0.xml generation event if there's a headers() call.

Running into this same issue with cookies()... sitemap-0.xml is only generated if the cookies() call is removed.

Same here when headers() are called on a not-found.js
