Google Cloud Saving Byte array Obsolete error

Hello, i am currently having an issue with the google cloud saving system. I believe i have all the serialization and deserialization scripts correct, but when i try to save or load anything, i get the following error saying that Byte paramaters are obsolote, and i should use SByte instead. I believe the issue is originating from the CommitUpdate() and ReadBinaryData() functions, but they only accept Byte as paramaters. I've searched everywhere for a solution but came up empty. Does anyone have similar issues? Is cloud saving just not compatible with unity yet?

SERIALIZATION/DESERIALIZATION

         }
     }
 
     //return saveString as bytes
     //https://stackoverflow.com/questions/1446547/how-to-convert-an-object-to-a-byte-array-in-c-sharp
     private byte[] ToBytes()

         using (var ms = new MemoryStream())
         {
             bf.Serialize(ms, playerInfo);
             Debug.Log("Saving " + ms.ToArray().Length + " bytes");
             return ms.ToArray();
             //return Array.ConvertAll(ms.ToArray(), b => unchecked((sbyte)b));
         }
     }
