Error in production but not caught by linter via pnpm build

Which project does this relate to?

Create Tanstack App

Describe the bug

I discovered a bug because I was trying to figure out why my code was building and deplying without errors then upon visiting the deployed website getting the response back from the url in return.

{
  "error": true,
  "url": "https://tanstack-start-deployment-bug.vercel.app/",
  "statusCode": 500,
  "statusMessage": "Server Error",
  "message": "Server Error"
}

I made a repo to demonstrate the issue

https://github.com/remusris/tanstack-start-deployment-bug

below is the deployment url

https://tanstack-start-deployment-bug.vercel.app/

Basically if you export a const from the a route into some component this will trigger the error in deployment.

If you look at the ComponentWithImportedZod.tsx file that is culprit of the issue

https://github.com/remusris/tanstack-start-deployment-bug/blob/master/src/components/ComponentWithImportedZod.tsx

If this is non an error please let me know what I'm doing wrong.

Your Example Website or App

https://tanstack-start-deployment-bug.vercel.app/

Steps to Reproduce the Bug or Issue

Export a const from a file inside of routes into a component outside of routes. In this case it was a zod schema for validating searchParams

Expected behavior

The user does not get any build errors or deployment errors but once the URL is live all you get in response is

{
  "error": true,
  "url": "https://tanstack-start-deployment-bug.vercel.app/",
  "statusCode": 500,
  "statusMessage": "Server Error",
  "message": "Server Error"
}

Additional context

No response

リンクされた再現リポジトリの src/components/ComponentWithImportedZod.tsx から始め、次に pnpm build を実行して、その結果をデプロイされた Vercel のレスポンスと比較します。route から外部コンポーネントへ const をエクスポートすると、デプロイ後に 500 エラーが発生する理由を追跡します。再現環境がその失敗状態でデプロイされなくなるか、ビルド中に問題が報告されれば完了です。
