I was assigned a P1 bug, and when I started to dig deeper into it, I found out that actual code was written by some other team and we have just used that code/object to build a small feature. I got a bit lucky that someone in my team told that the team ‘A’ owns that code/object. I was given a POC, but it turns out that they have left that team. I would like to have a POC to close out this bug.
For additional context: It is still not clear if it's the feature or the bug that's broken, that’s why we need to get clarification from the other team. Here's a high-level example to make things more clear: There is an object named "Product" which is a generic one, team ‘A’ built another object called "Product Category", and we added a field to that object. Now unless I ask some senior folks in my team it is really hard to understand who owns "Product Category".
Given all these unknowns, how can I navigate this situation and make sure this bug is resolved properly?
