#How to identify which URL is invalid on build time?

The error message you're seeing indicates that there's an invalid URL somewhere in your code, but it doesn't specify where. Unfortunately, the provided knowledge sources do not contain specific information on how to identify which URL is invalid at build time in Astro.
However, you can try to debug this issue by checking all the places where you're using URLs in your code. Make sure that all URLs are valid and correctly formatted. Also, check the dynamically generated JSON files you mentioned, as they might contain invalid URLs.
If you're using the Astro.fetchContent() function to fetch content from URLs, make sure the URLs are correct. Also, if you're using the Astro.resolve() function to resolve URLs, ensure the URLs can be correctly resolved.
If you're still having trouble, you might find it helpful to look at the Astro Documentation (https://docs.astro.build/), particularly the Error Reference (https://docs.astro.build/en/reference/error-reference/) section. This section provides information on various errors you might encounter while using Astro, which might help you diagnose the issue.
