Ошибка после срабатывания функции в ассоциативном массиве JS

У меня записан следующий код:

const Discord = require("discord.js");
const client = new Discord.Client();
client.login("NjM4Njk0ODQyMzg5NDk1ODQ5.XbgdAw.yMTBoGRiFSBEn0JtneLQgmq50Bc");
command = {
"/hello": function(message) {
    message.channel.send("Hello!");
},
"/help": function(message) {
    message.channel.send({
        embed: {
            color: 1274,
            description: "Help command activated!"
        }
    });
}
};
client.on("message", (message) => {
var comm = message.content.split(" ")[0];
command[comm](message);
/*if(message.content.startsWith("/help")) {
    message.channel.send({
        embed: {
            color: 1274,
            description: "Help command activated!"
        }
    });
}*/
});

И выдает следующую ошибку после выполнения первой функции:

    TypeError: command[comm] is not a function
