Exact behavioral answer
The mistake is not the point. What you do next is.
Interviewers want to know whether you can admit an error, take responsibility, correct it, communicate, and change your process so the same thing is less likely to happen again.

Examples
Food service
“During a busy shift, I entered part of a customer's order incorrectly. When they received the wrong item, I checked the receipt and realized the mistake was mine. I apologized, let the team know a correction was needed, and made sure the customer got an accurate update. Afterward, I started repeating unusual modifications back before finalizing the order.”
Retail
“I once gave a customer incomplete information about a promotion because I misunderstood one of the restrictions. When I realized it, I corrected the information and asked a supervisor to confirm the policy. After that, I made sure I checked promotion details before answering when I was not completely sure.”
Cashier
“While learning a register process, I selected the wrong option during a transaction. I told the supervisor rather than trying to secretly undo it myself, followed the correct process for fixing the transaction, and then asked them to walk me through the difference so I would recognize it next time.”
First job
“During a group project, I misunderstood one of our internal deadlines and realized my section would be late. Once I noticed the mistake, I told the group instead of pretending everything was fine, reorganized my schedule, and finished before the final submission. After that, I started putting project milestones into my calendar instead of relying on memory.”

Do not blame someone else
Context is fine. An indictment of your former coworker is not.
“I misunderstood the process and did not clarify before moving forward” is stronger than spending the answer proving someone else caused your mistake.
