Async line of code is like its invinsible - discord.js

Question

I dont know much of javaScript and i wanted to make a bot from a youtube tutorial. Now the video said to type this:
(async () => {
try {
if (process.env.ENV === "production") {
await rest.put(Routes.applicationCommands(CLIENT_ID), {
body: commands
});
console.log("Globally");
} else {
if (process.env.ENV === "production") {
await rest.put(Routes.applicationGuildCommands(CLIENT_ID, process.env.GUILD_ID)
, {
body: commands
});
console.log("Locally");
}
}
} catch (err) {
if (err) console.error(err);
}
})
Inside the client.once("ready",
So it turned out something like this:
client.once("ready", () => {
console.log("Bot is online.");
const CLIENT_ID = client.user.id;
const rest = new REST({
version: "9"
}).setToken(process.env.TOKEN);
(async () => {
try {
if (process.env.ENV === "production") {
await rest.put(Routes.applicationCommands(CLIENT_ID), {
body: commands
});
console.log("Globally");
} else {
if (process.env.ENV === "production") {
await rest.put(Routes.applicationGuildCommands(CLIENT_ID, process.env.GUILD_ID)
, {
body: commands
});
console.log("Locally");
}
}
} catch (err) {
if (err) console.error(err);
}
})
});
Now as you can see it says that if it finds client id it should type on console "Locally" to see if it works. But the terminal is like it ignores the whole async it just says that the bot is online nothing for the commands. What did i do wrong

Answer 1

Instead of defining a separate asynchronous function inside the ready handler function, why not just make the ready handler function itself asynchronous? Here's an example:
client.once("ready", async () => {
console.log("Bot is online.");
const CLIENT_ID = client.user.id;
const rest = new REST({
version: "9"
}).setToken(process.env.TOKEN);
try {
if (process.env.ENV === "production") {
await rest.put(Routes.applicationCommands(CLIENT_ID), {
body: commands
});
console.log("Globally");
} else {
await rest.put(Routes.applicationGuildCommands(CLIENT_ID, process.env.GUILD_ID)
, {
body: commands
});
console.log("Locally");
}
} catch (err) {
if (err) console.error(err);
}
});
That should allow the async function to run.
EDIT
Your if statements were slightly incorrect. You are checking if process.env.ENV equals production, and else, you are once again checking if it equals production. I've fixed that in this answer.
