Site has not yet been deployed message, but site HAS been deployed many times prior

Site Name : https://accountability-bunnies.netlify.app

Site was last published / deployed on Feb 18, 2024 with no errors.
No changes since then. But today I noticed the following error when reaching the url.

The netlify site overview says the site has not yet been deployed.

But the deploys page shows the successful deploys.

@ResearchScientist Since it’s a 500 error, you could try checking the Function Logs:
https://docs.netlify.com/functions/logs/

It may not help, but perhaps there is a clue there as to what’s occurring.

How about that. Looks like some kind of type error.

Pretty cryptic to me but wondering why it just started happening. I’ve made no changes since mid february.

It looks like you have a runtime request to fetch “something”.
That request is failing, and then the following code is dying due to that failure.

If it requests something that’s not under your control, then it could have changed on the other end.

Do you know what it tries to fetch?
