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"
}
