iOS receipt

Hi! I've update from version 1.23.1 to 1.23.2. And I faced with a problem - on version 1.23.1 i've parsed ios recept as

Code (CSharp):

1.                     var receiptDict = JsonUtil.Deserialize<Dictionary<string, string>>(product.receipt);
2.  
3.                     var payload = receiptDict[PAYLOAD_KEY];
4.  
5.                         var payloadDict = JsonUtil.Deserialize<Dictionary<string, string>>(payload);
6.                         developerPayload = payloadDict[DEVELOPER_PAYLOAD_KEY];
7.                         receiptData = payloadDict[RECEIPT_DATA_KEY];

And everything worked fine, but after the update, I stopped receiving a JSON. Now I receive some string. How can I get JSON as it was in the previous version?

Thanks! How can I decode it like it was in previous version? I need to get 'developerPayload' and 'receiptData' to validate them on my server
