Cannot invoke "Object.getClass()" because "soundType" is null

[Schnell1337]

When I use boat in minecraft client version 1.8, I get something like this: https://www.youtube.com/watch?v=7jNjXTXRV9o

Error in the console: https://pastebin.com/VCn6WmVR

For example, when you use 1.12.2 and above, everything is fine

Server version: paper 1.12.2

Latest version of ViaRewind Legacy Support: 1.4.2

It has the same problem with 1.12.2.

[Howard ZHY]

Did you use latest ViaRewind from Jenkins?

@HowardZHY I am using ViaRewind@49e72d487cf0ea5e747dbf109c4c1efd70a046a2.

Same exact problem. This seems to lead to a crash.
Server: Paper 1.12.2
Client: 1.8.x
