Custom Command crash on 1.21 client

[EssieFir]

Minecraft 1.21
Command Aliases version: 1.0.1
Only Command Aliases and Fabric API installed.

Placing this inside the client folder for command aliases and then executing /test will crash the game.

{
  "schemaVersion": 1,
  "commandMode": "COMMAND_CUSTOM",
  "command": "test",
  "message": "test 1",
  "actions": [
      {
          "command": "say test",
          "commandType": "SERVER",
          "startTime": "1000",
          "message": "test 2"
      }
  ]
}

Setting commandType to "CLIENT" results in /say test being printed into the chat instead of it being executed.
