LiveryQuery server response sends data or events in "object":jsonf= format but PFDecoder.m checks for __type key which is missing as shown in below example so this fix will add "__type ":"Object" key-value if dictionary has className and objectId representing PFObject.

"object":{ "desc": "Technology", "createdAt": "2020-10-03T19:34:16.823Z", "updatedAt": "2025-09-27T17:55:02.360Z", "image_name": "technology.png", "className": "categories", "objectId": "kHnBntWHHW" }, "original": { "desc": "Technologyy", "createdAt": "2020-10-03T19:34:16.823Z", "updatedAt": "2025-09-27T17:54:10.800Z", "image_name": "technology.png", "className": "categories", "objectId": "kHnBntWHHW" }
