Fix GenerateContentTypesError

in Astro

Solution

The "GenerateContentTypesError" in Astro typically arises from server-side modules (like `node:os`) being used directly within client-side code or content collections. To resolve this, either move the server-side logic to an API endpoint accessed via `fetch`, or use a conditional import/require statement, ensuring the server-side code is only executed during the build process or in a Node.js environment. Specifically, dynamic imports with environment checks (e.g., `import.meta.env.SSR`) are useful for conditionally importing server-side modules.
