> This was caused by a gap between old client and server on (de)serializing the expression. In old client, we don’t stream the expression’s class type into bytes, while the server should read the class type from serialized bytes firstly, which makes the trouble. Other APIs that need to (de)serialize expression may be suffered as well.
