Serverless can’t fetch all records Event object failed validation?

I am trying to fetch all records using query and JSON schema but I am keep getting Event object failed validation unless I pass a query it didn’t give me any result.
I am trying to fetch all the records that have status=OPEN
I set the default value of status=OPEN but it looks like default value is working.
Unless I pass the status=OPEN as a query
Please help me!!!
