🛠️Fix a bug in AIException constructor (#717)

The AIException constructor that takes an errorCode, a message, and a
detail was incorrectly passing null as the detail parameter to the base
constructor. This commit fixes this bug by passing the detail parameter
correctly. This ensures that the detail information is preserved and
available for error handling.
