The latest version of Paper does not display PlayerCount correctly

[RomaYT]

Expected behavior

The text "Hello" should be rainbow.

Observed/Actual behavior

I downloaded the plugin, installed it and changed PlayerCount

Steps/models to reproduce

1. Downloaded the latest version of the kernel https://papermc.io/downloads.

2. Threw it into the folder.

3. Threw the plugin AdvancedServerList-Paper-5.7.0-b2 into the plugins folder

4. Went to advancedserverlist >> profiles >> default.yml

Changed the file, adding the following to it.

profiles:
  - motd:
      - "<bold>Hello<reset> World!</reset>     "
      - ""
    playerCount:
      text: '<bold>Hello<reset> World!</reset>     '
      hover:
        - ""
  - motd:
      - "<rainbow><bold>Hello<reset> World!</reset>     "
      - ""
    playerCount:
      text: '<rainbow><bold>Hello<reset> World!</reset>     '
      hover:
        - ""

and when I launched it I got an incorrect PlayerCount display.

Other

Below I have attached a screenshot of the problem, at the top are 2 servers on Velocity with the same plugin and PlayerCount working almost correctly, at the bottom are two paper servers with PlayerCount not working correctly.

the creator of the plugin replied to me Andre_601 — 20:13 It's certainly an issue with the Adventure library Probably with the legacy text serializer As I have to convert MM tags into a String with the legacy code as MC doesn't support Chat components for the player count

I don't see a problem here.
The "PlayerCount" is actually a string representation of the server version, that does not, as the author of the plugin said, support text components.
This is not caused by Adventure, just a client "limitation" if you want to call it that.

Will keep open until we publish 4.24.0 and update paper.

Не вижу здесь проблемы. «PlayerCount» — это строковое представление версии сервера, которая, как сказал автор плагина, не поддерживает текстовые компоненты. Это не проблема Adventure, а просто «ограничение» клиента, если можно так выразиться.

But then why on proxy (velocity) It works better? Although the plugin is the same..

I assume you are replying to my message.
I didn't notice that the motd is bricked as well, I thought just the version string.
The plugin probably uses adventure-platform-bukkit, that's why the components are serialized differently.
Velocity has native adventure support and the paper version of the plugin probably has spigot support which does not.
