Description
Tested on:
- 1.19.4
- 1.20.2
- 1.20.4
I get UnsupportedOperationException when calling MinecraftComponentSerializer.get().serialize(component); on villagers names trade GUI name and some other texts.
Only way to fix that is to convert the adventure Component to Json String and use NMS to convert the Json String to Minecraft MutableComponent, I tried that and works fine.
Seems the issue is somehow caused by the json tree -> MutableComponent implementation.
