Plugin and Datapack List

• bluemap-5.13-paper

Actions to reproduce (if known)

1. install BlueMap
2. have at least one player logged into server
3. issue minecraft:players/kick over the management server API:

{
  "id": 1,
  "method": "minecraft:players/kick",
  "params": {
    "kick": [
      {
        "message": {
          "literal": "testing",
          "translatable": "",
          "translatableParams": []
        },
        "player": {
          "id": "8a56e8f2-0bc0-42aa-8f20-7b9188d1efbc",
          "name": "glob"
        }
      }
    ]
  },
  "version": "1.0"
}

Paper version

This server is running Paper version 1.21.10-113-main@9fc21bc (2025-11-14T16:11:13Z) (Implementing API version 1.21.10-R0.1-SNAPSHOT)

Other

Expected result

• player is kicked from server
• RPC call returns success

Actual result

• player is kicked from server
• RPC call returns {'code': -32603, 'message': 'Internal error'}

Start with net.minecraft.server.jsonrpc.methods.PlayerService.kick and follow the disconnect path through ServerCommonPacketListenerImpl, ServerGamePacketListenerImpl, PlayerList, Entity, and EntityScheduler. Reproduce the minecraft:players/kick request with BlueMap installed and a logged-in player. Done means the player is kicked and the RPC returns success instead of an Internal error.
