ISR doesn't seem to work

[chandragie]

Description

I noticed that ISR does not work after deploying, I'm on Vercel.

The build logs however says it's active:

However, once the app is deployed, the changes in Notion never applied. I tried changing the revalidate value but no luck.

Same issue here

I was thinking maybe we could add a manual revalidate in order to trigger revalidation instead of having to deploy every time.

did you get it working?

Yes, I feel like the issue is not with this repo. Its Vercel. I think for some odd reason the revalidate doesn't work on the free plans. It considers ISR pages as SSG and only rebuilds them at build time. When I deployed the same website on my own VPS, it seemed to revalidate correctly.

What? Really? I must have missed the updates. ISR seems supported in free plan in my first Next project in 2022.
On Vercel, I always get the 500 error complaining about sharp packages. Duh

@mabdullahabid it's working now.
So, apparently ISR didn't work because of sharp error on Vercel. Fixed it and now everything including ISR works.
Here how I solved the sharp problem: #618 (comment)

Closing this issue now.
