Where are NextJS API logs? Specifically for Deploy Previews?

I was looking there because the __netlify-handler logs were empty.

I just tried again, and I am able to see production logs there - it’s a bit confusing because the real time logs don’t actually work as I expected. They only seem to show logs since I visited the page, which I found confusing, I expected that “real time” just meant they would update in real time. Not that they would only show logs since I landed on the page.

Regardless, deploy preview logs are still not there. Where are those located?

The only information I could find on the subject was here:

which references “serverless functions” which is no longer a tab in admin. I could find no mention in the docs as to where to expect these logs to exist. I don’t find the naming particularly clear, why would I expect the logs to be under “__netlify-handler”? I see now during deploy that functions are deployed:

8:05:01 AM: Packaging Functions from .netlify/functions-internal directory:
8:05:01 AM:  - ___netlify-handler/___netlify-handler.js
8:05:01 AM:  - ___netlify-odb-handler/___netlify-odb-handler.js
8:05:01 AM:  - _ipx/_ipx.js

but it is very unclear what any of these do or what do expect in each log.
