Execution Details:
(Cycle #1) [Integrity Manager user-defined answer] failed: 날짜 또는 시간 값이 필요합니다.  // Date or time value are required.
[Integrity Manager internal answer] failed: 날짜 또는 시간 값이 필요합니다. // Date or time value are required.

Cause

This is a known issue in Strategy Strategy Integrity Manager 2021 All version, Strategy ONE March/June/September 2024.

Action

Suggest to use the workaround by forcing Integrity Manager to work in English locale. 
Add a environment variable: JAVA_TOOL_OPTIONS
With value: -Duser.language=en -Duser.country=US

• It will override the default JVM locale. The user will use English locale on Integrity Manager no matter what the OS language is set.
• In this way, the custom prompt answer should also use the English pattern "MM/dd/yyyy"
