How can I use `getStaticPaths` correctly to avoid prerendering errors with dynamic routes?

When using dynamic routes (e.g., `/blog/[id]`), `getStaticPaths` must return an array of paths that Next.js should prerender. If a path is not included in this array, Next.js won't prerender it, and accessing that route will result in a 404. Ensure your `getStaticPaths` function accurately generates all necessary paths.
