Hi guys,

Please look at my message declaration. I have Avatar and NetworkEntityState message

When player join a match, i load Avatar from StorageEngine and send to client in a NetworkEntityState message. This is jsonValue of avatar

But in the log of Unity, the field type of object Avatar was changed from number to string. So an exception was threw

```auto
MatchStateJson [{"states":[{"id":"72a21b7a-380c-4b23-9ac6-abe12b4c5573", "username":"GSzGbaQbJB", "yPos":1, "state":"1", "avatar":{"hair":"6"}}]}]

```

Please help me to explain this issue.

It looks like int64 types are treated as strings by the specific marshaler you are using.

I found it. I followed template project and used protojson to encode and decode message.  
I also changed it to proto, and now it’s worked.
