seems to be not working for 1.21.1

[soziopath]

added config/commandaliases/survival.json:

{
    "schemaVersion": 1,
    "commandMode": "COMMAND_REDIRECT_NOARG",
    "command": "survival",
    "redirectTo": "gamemode survival"
}

did /commandaliases reload
execute ingame : /survival

output: "Unknown or incomplete command ..."
