It happened to me few times: - We got a "400 bad request" because we received a UUID for something that wasn't even supposed to be a UUID. I had to fish around for what this UUID was actually referring to, to track down the bug. It was an integration with a partner, and some faulty branching logic. - We ask our customer support team to add IDs to engineering support request (customer ID, order ID, etc etc) so that we don't lose time. Sometimes they make a mistake (or it's not always clear what they're supposed to do) and we get a user ID that doesn't refer to any user. Bit of fishing around then again - Wild logs: "could not find entity f5fac1d0-5d0f-11eb-9ab7-3e22fb071270". I'm sure I could find more example but you get the gist of it
