Describe the Bug

If I went into an MDX file and removed an import accidentally, I saw this error message. This message made no sense since there was no Content component or variable defined, and it didn't tell me the file name either.

If I started the dev server with this missing import, the dev server crashed and failed to startup.

 error   Unable to render Content!
  
  There is 1 renderer configured in your `astro.config.mjs` file,
  but it was not able to server-side render Content.
  
  Did you mean to enable `@astrojs/react`, `@astrojs/preact`, `@astrojs/vue` or `@astrojs/svelte`?
