"hostname" and "port" must be provided when starting next to use "unstable_revalidate"

Issue Summary

I want to use req.unstable_revalidate for ISG. Reading here it seems supported.

Actual behavior

If I call req.unstable_revalidate inside an api I got this error:

"hostname" and "port" must be provided when starting next to use "unstable_revalidate". See more here https://nextjs.org/docs/advanced-features/custom-server

I can't get any actual information about this problem at the provided url. Also, checking the code generated inside .next/serverless/chunk/ I don't think I can pass hostname and port parameters, because the function accept only one parameter:

apiRes.unstable_revalidate = (urlPath)=>unstable_revalidate(urlPath, req, apiContext)

Looking for the round of calls that are made previously, I don't even seem to be able to modify this apiContext.

(Locally works fine)

AFAIK base ISR feature is working where you add the revalidate prop to getStaticProps. If you are referring to 12.1 release's On-demand Incremental Static Regeneration, it should not be working.

So this happen to me if I am using a custom server, if you do then make sure you have const app = next({ dev, hostname, port }) with hostname and port

check https://nextjs.org/docs/advanced-features/custom-server for more info

@thmohd I am using Serverless Stack (sst) which uses serverless-next.js, maybe I should open an issue to them? Can you confirm that ISG with unstable_revalidate should work on the serverless-next.js side?

(I do not create any custom server and it is not clear to me if the custom server is created by sst or by serverless-next.js)

Hi, Do you know if there is any plan to add this feature?

Any update?, trying to use On-demand ISR gives me "Invariant: required internal revalidate method not passed to api-utils"
