  • Closed as program error.

Error description

  • It has been identified that putting a "/" before the index
    doesn't invalidate the match when testing JSON expressions in
    the Custom Event Property UI (CEP). This can result in false
    positives in the CEP UI.
    Example:
    /"object"[0]/"desiredPropertyName"   <-- correct
    /"object"/[0]/"desiredPropertyName"  <-- incorrect
    Note the second expression has an extra "/", the CEP UI will
    generate a false positive match, which will result in seeing
    "N/A" when an event is processed through the pipeline
    

Local fix

  • Ensure the correct expression is being used. Not all expressions
    that provide a result while using test button in the QRadar User
    Interface provide the expected results when events are
    processed.
