Describe the Bug

When the live Astro dev server is running, attempting to move any folder containing an image out of a content collection will break it and cause a build failure.

On StackBlitz, you should get something like this:

What's the expected result?

The Astro dev server should not crash and not have a build failure if a piece of content is removed from the collection that references images

I'm not sure I understand the problem.

You have a content collection that has an image and you render it. Then you move the file somewhere else and Astro tells you it can't find the image (you didn't update the file path in the schema of the collection).

Why is this incorrect?

@ematipico that's not what I meant. Instead of the single image file, move out (or delete) the entire test-post directory and observe that the build still breaks. I do expect to get a 404 if the entire page is gone, but the build continues to fail until the dev server is restarted and the content collection is resynced.

For context, with a folder structure like this:

content/
  blog/
    some-blog-post-here/
      index.md
      image-1.png
  drafts/
    draft-blog-post/
      index.md
      image.jpg

and a single blog content collection, the bug makes it so that I can't quickly preview my draft posts by moving the draft-blog-post folder between drafts/ and blog/. Adding it to the blog/ is fine since additions seem to trigger a resync of the collection, but once I remove it again from the blog/ folder to the drafts/ folder then the build breaks for the entire blog collection until I restart the dev server.
