Please review how JavaScript arrow functions work: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions

Currently your registerChatInputCommand method isn't returning anything so the error is that you're providing undefined where string was expected, which is for name because you're not actually setting it. You need to either remove the wrapping { } or add a return keyword.

One of these 2:

public override registerApplicationCommands(registry: Command.Registry) {
    registry.registerChatInputCommand((builder) => {
        return builder.setName('help')
    });
}

public override registerApplicationCommands(registry: Command.Registry) {
    registry.registerChatInputCommand((builder) =>
        builder.setName('help')
    );
}

Sidenote that you really dont need a help command when using slash commands btw because the list of commands is integrated in the Discord client when the user types a single /

[slim bloom]

wait what's wrong with my arrow function
