Bug: Internal Server Error (500) in `/table/cities`

When I visit https://fastui-demo.onrender.com/table/cities to view the FastUI table, I encounter the following error message:

Request Error
Internal Server Error (500)

Although I can see the table results initially, the page redirects me to the homepage while keeping the URL in the browser's address bar. If I try accessing the URL again, the error appears once more.

Steps to Reproduce

1. Visit https://fastui-demo.onrender.com/
2. Click the Table tab
3. The error occurs
