(SOLVED) - Error key not run in .ajax function

#1

Hi,

I almost completed my Twitch API project but I am not able to catch non-existent users.
I tried logging them but these users are still appended onto my table.

#2

I realized that I cannot simply add a random username but when I added comster404 and brunofin into my stream array, I finally got the error that I was looking for.
