Unexpected Execution of generateSitemaps Function When Commented Out During Build Process

[Akramovic]

Link to the code that reproduces this issue

https://codesandbox.io/p/devbox/elegant-surf-z8vmmj?file=%2Fapp%2Fsitemap.ts%3A7%2C25

To Reproduce

1. Add the generateSitemaps function to your sitemap.ts file.
2. Comment out the generateSitemaps function.
3. Execute the build process and notice that the build does not succeed, suggesting that the build process is impacted by the commented-out code.

Current vs. Expected behavior

Expected Behavior:
Commenting out the generateSitemaps function should not impact the build process
Actual Behavior:
The generateSitemaps function appears to be parsed resulting to a build error.

I have similar bug. I need this to be dynamic sitemap (it accesses database), and yet force-dynamic doesn't stop this from execution during build process.

Is there a way to fix it? It seems that now multiple-sitemaps generation will always happen in build time. I am building Fraghead.io which uses Prisma (Postgres) backend, so I do not have access to any data in build time.

Temporary fix:
I have encapsulated both functions in try {} catch {}. They will run during build time and fail silently but fortunately they will be dynamically generated in the runtime as well, making it work.

Still, would be better to not call it in build time.
