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
> tanstack-experiments@ dev /Users/aalmacin/Projects/tanstack-experiments
> vite dev --port 3000

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:
