Describe the Bug

Somewhat similar to #6335, when running the Node adapter in standalone mode and a base path is set, going to the url of the application without a trailing slash returns 404. This is my Astro config:

export default defineConfig({
  base: "/base-path",
  trailingSlash: "ignore",
  integrations: [react()],
  output: "server",
  adapter: node({
    mode: "standalone",
  }),
});

The only working version of the app both in dev and preview is with a trailing slash, even when trailingSlash is set to ignore. That is, http://localhost:3000/basepath returns 404 and http://localhost:3000/basepath/ does not.

It looks like a trailing slash is added during build under const _manifest in dist/server/entry.mjs: ... "_meta":{"trailingSlash":"ignore"}}}],"base":"/base-path/
