Describe the Bug

Astro supports a redirects field in astro.config. According to our docs this should be able to support dynamic routes:

Dynamic routes are allowed as long as both the new and old routes contain the same parameters

I’m seeing errors for each of the following cases:

  redirects: {
    '/old/[...spread]': '/new/[...spread]',
    '/old/[dynamic]': '/[dynamic]',
    '/old/[dynamic]/[route]': '/[dynamic]/[route]',
  }

In each case, attempting to load a route from one of the /old/ paths, throws:

getStaticPaths() function is required for dynamic routes. Make sure that you export a getStaticPaths function from your dynamic route.

The dynamic routes at the new location each contain getStaticPaths().

What's the expected result?

Dynamic redirects containing the same parameters redirect to the new location as expected.

Just to confirm, this is a dev-mode only issue?
