Today morning my sales manager calls me and tells there is a bug in one of the integration module and he tells the client has called us yesterday pls come early to office today and fix it. I asked which end point they have issue, he replies I don't know. I don't know what is the bug where is the bug, but there is a bug when they send data to us, pls find and fix it before 11 am. The worst part of this is that integration module I never worked on and the person who developed it has left the company long before and there is no documentation. when I go to that folder I see many controllers and many end points. now how will I figure out the issue 😂 I don't even know the work flow of that integration. the bug reporter (my sales manager) don't even know at what end point what issue happened.
