CR04 patch was applied to API Gateway v9.3.00.
After that, below WARNING message is written in ssg log file about every five minutes:
Product: API Gateway v9.3.00 CR04 (On-Premise)
The property ‘jsonEvalJsonPathAcceptEmptyArray’ was added in CR04, but Boolean validation type is missing for it. It is same property as ‘json.evalJsonPathAcceptEmptyArray’ reflected with dot.
You can ignore, only thing is Gateway will not validate the value of json.evalJsonPathAcceptEmptyArray.
We will address this in CR05.
