Client Crash/disconnect when playing music near RainFrogs

[Boombastick4]

When trying to play a music disc(weather it's the vanilla or any other custom discs from other mods) near RainFrogs to make them dance, the game "disconnects" me from the world. This issue can be replicated in a singleplayer and multiplayer.
This is the message i get when it crashes:
io.netty.handler.codec.EncoderException: Failed to encode packet 'serverbound/minecraft:custom_payload'

• How to replicate

1. Create a world
2. Get a bunch of rainfrogs, a jukebox and a music disc
3. Play music disc
4. Crash

Anyone the cause, or how it might be fixed?

No. Tried to repeat it and nothing happened. Try it with just Alex's Mobs.
