The goal is for you to tell them what you did and learned about from that negative experience. tell me about a time when you failed. I was asked if I could do ABC with a certain amount of time, and I said sure I would get it done, I was sure of A and C but I couldn't figure out B. so I set out to figure out B, I asked for help and no one knew how to solve B, so I went through XYZ process to figure out B, it took longer than I thought, I communicate that I would miss the deadline, I finally figured out B after taking a crash course, but I missed the deadline and was pretty embarrassed by that. I learned that I shouldn't promise to deliver on a hard deadline when there are unknowns, however to my surprise, the client was understanding since I communicated ahead of time that I might ship late. I also learned to keep an open communication and communicate progress and expectations while working on something. These questions are not traps, they are asked to extract your experience. It's also a good way to demonstrate your communication skills through story telling, it needs to be succinct.
