Description
Hey, i'm updating my project for use your new feature 'MsgPack', after 1 day i'm okay with the new API and i try to use this feature. I can serialize without any problem but when I try to deserialize, and serialize in json format this time, my json is empty. I think i don't understand the API or idk, someone can help me ? thanks.
