Describe a time when your code failed in production. What did you learn?

I am preparing for software engineering interviews and came across this behavioral question. I understand that interviewers want to assess problem-solving skills, ownership, and the lessons learned from real-world incidents.

Could someone explain:

What is the interviewer looking for when asking this question?
How should I structure my answer using the STAR (Situation, Task, Action, Result) method?
If I have never worked on a production application, how can I answer this question honestly using an internship, academic project, or personal project?
What are some examples of production issues, such as deployment failures, API errors, database issues, or unexpected bugs?
What key lessons or best practices should I mention to demonstrate growth and accountability?
