Creeper - await and username

[fringe sable]

That code gives me a headache 😄
And what's the error?

[mortal plinth]

well if the client.users.fetch() has an invalid id passed

then the whole app crashes

so i want to make the value null if it doesn't return a value

but i am not sure how to do that

[fringe sable]

So it's that the fetch errors, or returns undefined?

[mortal plinth]

yes the error is coming from the fetch

if i do fetch('123') i want it to return null but instead it crashes the whole app

[fringe sable]

You're 100% fetch itself is throwing an error, not that because it returns nothing, .username then errors?

Do you have the error trace?

[fringe sable]

You sure the Id is a User Id, sounds like you made a magical Id

[mortal plinth]

i made the value an invalid id but i want to make it so it doesnt crash to program and instead it returns null

like the username variable should be equal to null

it used to work when i used to use client.users.cache.get() because that is not a promise and it just returns null if there is no value but then i noticed that i need to use .fetch() instead and now i get this error

[fringe sable]

In this case if you want to protect it from erroring, just move the username 1 out.

and put it in a try catch

let username;
try {
  username = (await ...)
} catch (error) {
  username = 'N/A';
}
