CORS issue with build when using DDEV (docker)

[tyler36]

I finally got around to giving this is a good go on CakePHP5.
However, I'm hitting a CORS issue when I run build, but not dev.

I'm using DDEV to serve my CakePHP and have the following vite.config.js

const port = 5173
const origin = `${process.env.DDEV_PRIMARY_URL}:${port}`

// https://vitejs.dev/config/
export default defineConfig({
  build: {
    emptyOutDir: false,
    outDir: './webroot',
    manifest: true,
    rollupOptions: {
      input: './webroot_src/main.ts',
    },
  },
  server: {
    host: '0.0.0.0',
    port: port,
    origin: origin,
    strictPort: true,
    watch: {
      usePolling: true,
    },
  },
})

combined with app_vite.php

return [
    'ViteHelper' => [
      'development' => [
        'hostNeedles' => [
          'localhost',
           '.site'
        ],
        'url' => 'https://cake5-vanilla.ddev.site:5173',
      ],
    ],
];

This works when I run dev.
When I use build, it sees .site in the host and thinks its running a DEV server and fails. If I comment out the hostNeedles, build works but dev does not.

Not sure where exactly the issue lies, but any insight would be helpful.
