Astro: Redirect routes cause some directories to fail matching on S3

[Zach Cardoza]

The issue appears to be that the redirect routes in the meta file cause a tree branch in the CF Function matching logic which terminates without looping back to the catch all slug.

Ref sst.buildMeta.json:

  "domainName": "",
  "deploymentStrategy": "regional",
  "responseMode": "buffer",
  "outputMode": "hybrid",
  "pageResolution": "directory",

    {
      "route": "/harrypedia/culture/contracts",
      "type": "redirect",

      "redirectPath": "/harrypedia/magic/contracts/"
    },

    },
    {
      "route": "/[...slug]",
      "type": "page",
      "pattern": "/^(?:\\/(.*?))?\\/?$/",
      "prerender": true
    }
  ],

}

While investigating this issue, I uncovered a change in the Astro routing priority logic which causes further issues in the route matching.

Ref: Astro #9439

The result is that redirects are now matching below spread routes which won't allow the redirect routes to be picked up correctly.

    {
      "route": "/",
      "type": "page",
      "pattern": "/^\\/$/",
      "prerender": true
    },
    {
      "route": "/[...slug]",
      "type": "page",
      "pattern": "/^(?:\\/(.*?))?\\/?$/",
      "prerender": true
    },
    {
      "route": "/blog/fourth-post",
      "type": "redirect",
      "pattern": "/^\\/blog\\/fourth-post\\/?$/",
      "redirectPath": "/blog/third-post/"
    },
    {
      "route": "/old-blog",
      "type": "redirect",
      "pattern": "/^\\/old-blog\\/?$/",
      "redirectPath": "/blog"
    },
    {
      "route": "/old-blog/[...slug]",
      "type": "redirect",
      "pattern": "/^\\/old-blog(?:\\/(.*?))?\\/?$/",
      "redirectPath": "/blog/[...slug]"
    }

the global routes option did not help.

I confirm that PR fixed this.
