What do you do when you find an error that is not related to your area of responsibility?

If I discover a bug that is not within my area of responsibility, I first document all the details of the issue: what exactly happened, under what conditions, and any logs or error messages available. Then I report this to the responsible colleagues or team that handles the relevant area, providing them with all the collected information to expedite the resolution. If necessary, I can assist with diagnosis or testing, but I do not take responsibility for fixing it to avoid overstepping boundaries and causing conflicts within the team.
