alt Hacker NewsThe only thing I remember about CORS is that it takes way longer than expected to debug, by design the error messages sent to the browser are intentionally gutted, and CORS error scenarios are hard to tell from other failure modes atfirst glance.

A CORS error is not "an error message sent to the browser", it is an error generated by the browser, because the browser has decided it cannot permit the request. (Though certainly a server can not understand a CORS request as such, and returned a weird response, which would then end up getting translated to a CORS failure.)
