Deploy with vercel throws 'This Serverless Function has crashed.'

Hi I'm trying to deploy my project with vercel. I can run well in my local, and build successed. But, when I deploy to vercel, 'This Serverless Function has crashed.' are shown. I already set deploy target to 'vercel' in my vite.config.js. What should I do? 😿

Oh, the first question was my fault (__dirname is not defined in ES module) so I corrected it. But, other problem is occuered.

And This is my vite.config 
// https://vitejs.dev/config/
export default defineConfig({
  server: {
    port: 4000,
  },

  plugins: [
    react(),
    tsconfigPaths({
      root: path.resolve(__dirname, '.'),
    }),
    relay,
    sentryVitePlugin({
      release: {
        name: SENTRY_RELEASE_TARGET,
      },
      ...(IS_PRODUCTION && {
        sourcemaps: {
          filesToDeleteAfterUpload: ['**/*.js.map'],
        },
      }),
    }),
    tanstackStart({
      customViteReactPlugin: true,
      target: 'vercel',
    }),
    cjsInterop({
      dependencies: [
        '@sentry/react',
        'react-relay',
        'relay-runtime',
        'react-lazy-load-image-component',
      ],
    }),
  ],

  build: {
    sourcemap: true,
  },
});
