Discord. js bot reconnecting For some reason, when I leave my bot on for a while, it disconnects every few hours, and reconnects. I have a monitor open that is keeping track of the status and pings the program to keep it awake. Any ideas?

Which of the following exceptions could occur when the following code is run, if the precondition is met? // precondition: a is not null public string dosomething(arraylist a, int b) { int i; string s; for (i = 0; i < = a.size(); i++) { s = (string)(a.get(i)); if (s.length() == b) { return s; } } return null; }
