Crash when ranking.ranking.rank_id = NULL

[Bl4CkGuuN]

My bot is crashing when it wants to check a profile, who didn't got a csgo rank.

How can I prevent that?

Some of my code:

csgo.setMaxListeners(50);
csgo.requestPlayersProfile(account_id, function(ranking) {

var rankid = ranking.ranking.rank_id;
var wins = ranking.ranking.wins;
var private = ranking.player_level;

if (rankid == 0) {
      var rank = "Unranked";
} else if (rankid == 1) {
      var rank = "Silver 1";
}  else if (rankid == 2) {
      ...
} else {
      var rank = "";
}

"Crash":

                var rankid = ranking.ranking.rank_id;
                                             ^

Why don't you check the response of your request? It errors, if the Response is NULL, so why don't you check if the response has Data before setting a variable?

Because I have absolutely no idea what I'm doing, also I hate js :D

ranking.ranking is null, and trying to access a property of null is an error. You need to first check whether ranking.ranking is not null.
