TanStack Start ISR in Vercel

[agustinusnathaniel]

I was looking through the ISR documentation https://tanstack.com/start/latest/docs/framework/react/guide/isr

Then I tried to follow the guide

• I defined the cache-control https://tanstack.com/start/latest/docs/framework/react/guide/isr#vercel
• the docs also stated it could be combined with prerendering https://tanstack.com/start/latest/docs/framework/react/guide/isr##5-combine-with-static-prerendering

But after I tried to deploy it on Vercel, it stay static forever (not re-render updated static page after max age duration)

Then I tried disabling the prerender config and just adding cache-control, and it works as expected

Is this expected? On vercel we can only rely on the cache-control header (can't combine it with static prerendering)?
If that's the case, I think the docs should be updated to add notes on combining it with prerendering that it won't work on Vercel.
