Issue: UXP Environment Cannot Resolve Rollup Code-Split Chunks

Problem Description

When building a UXP plugin with Vite and Rollup code splitting, the generated chunks cannot be resolved properly in the UXP environment. The error occurs when the main entry file tries to import the vendor chunk:
uxp://uxp-internal/domjs_scripts.js:2 Uncaught Error: Module not found: "./vendor.js". Parent module folder was: "./"

Environment

• Build Tool: Vite
• UXP Plugin: vite-uxp-plugin
• Framework: Vue 3
• Code Splitting: Rollup manualChunks

Configuration

// vite.config.js
export default defineConfig({
  build: {
    rollupOptions: {
      output: {
        manualChunks: (id) => {
          if (id.includes('node_modules')) {
            return 'vendor';
          }
        },
        format: 'cjs',
        chunkFileNames: 'assets/[name].js',
        entryFileNames: 'assets/[name].js',
        assetFileNames: 'assets/[name][extname]'
      }
    }
  }
});
