You send an HTTP request and get back an HTTP error but with an HTML error page which you didn't expect... what's happening?... 🤔
Specifically for example, perhaps you tried to READ a FHIR Resource (e.g. /Patient/123) and you get back a 404 error page, even though with other Patient IDs, you get back the Resource payload, so "the page" definitely does exist... why should you be getting a 404 error page? 🙄
