TypeError: selector is not a function

使用 pnpm create @tanstack/start@latest 复现生成的应用，选择 Netlify 以及 AI、DB、Form、Query，然后运行 pnpm dev。从 src/components/demo-AIAssistant.tsx:82 开始，跟踪服务器渲染期间失败的 useStore 调用；当示例主页能够在没有 TypeError 的情况下加载时，即表示完成。

Which project does this relate to?

Describe the bug

This is my first time trying out tanstack start and I run into an issue trying to run the app with pnpm dev.

I chose AI, DB, Form, Query and I also chose Netlify

Here are the logs:

Initially looks like everything is ok

❯ pnpm dev

But I am getting {"status":500,"unhandled":true,"message":"HTTPError"} on the browser when I tried to open http://localhost:3000/. On the terminal it shows:
