Cannot read property 'type' of null

Hi, sometimes this happens:

Offer #1248497400 changed: CreatedNeedsConfirmation -> Active
/home/nodebots/node_modules/steam-user/components/web.js:9
  if (this.steamID.type === SteamID.Type.ANON_USER) {
                  ^

TypeError: Cannot read property 'type' of null
    at SteamUser.webLogOn (/home/nodebots/node_modules/steam-user/components/web.js:9:18)
    at tryOnTimeout (timers.js:224:11)
    at Timer.listOnTimeout (timers.js:198:5)

Whats wrong?

You're calling webLogOn while you aren't logged onto Steam.

I calling it when event sessionExpired is emitted so whats wrong?

bots['community'].on('sessionExpired', function() {
	bots['client'].webLogOn();
});

[Dr. McKay]

You got disconnected from Steam, and that's why the session expired.

So when event sessionExpired is emitted i should use logOn method or what?

[Dr. McKay]

It depends on why you were disconnected. If the error event was emitted then it was an unrecoverable disconnection and you need to reconnect yourself. If the disconnected event was emitted instead, then steam-user will automatically reconnect.

 

Basically, you just shouldn't webLogOn if you aren't currently connected.
