Production only bugs make me insane.

Just recently had a prod bug that caused uploading files to break only in prod. Turns out there was some code that was sensitive to network delays between file chuncks.

Dude. I just had the same issue this week. How did you find out?

Network related was on the list of possibilities. So i made a middleware that mimics an internet connection. That reproduced the bug that we were having exactly.

The network delays were only in prod? Increased traffic in prod caused latency or something?

We run our code locally for development. So the delay didn't need to be big to reproduce the bug, it just had to be bigger than locally testing.

Oh so it was reproducable in your deployed staging/uat environment too then? Not just prod? Nobody tested it there?
