Minecraft recently added support for representing the UUID in a `show_entity` hover event as an array of integers.
BungeeCord chat was already updated for this: #3578: bungeecord-chat does not support array format UUIDs · SpigotMC/BungeeCord@b711e40 (github.com)
But it seems Spigot is still on an outdated version, tested with the following JSON string & code:
{"text":"test","hoverEvent":{"action":"show_entity","contents":{"type":"minecraft:cow","name":"A cow","id":[410807316,673401202,-1461765392,1569381605]}}}
Bukkit.dispatchCommand(sender, "tellraw @p " + JSON); // Works fine sender.spigot().sendMessage(ComponentSerializer.parse(JSON)); // Errors
The tellraw works as expected and shows up in chat, but the ComponentSerializer#parse call throws the following exception:
