Cannot read property 'webLogOn' of undefined

[Trajko]

Hi, how can I fix this:

Error: 

 this.client.webLogOn();
                        ^
TypeError: Cannot read property 'webLogOn' of undefined

Code: 

        this.community.on('sessionExpired', function() {
            this.client.webLogOn();
	});

This code is inside SteamBot constructor class

Inside of that callback function, this refers to the SteamCommunity instance and not the outer context's this. Replace that with an arrow function and it should work as you expect.

this.community.on('sessionExpired', () => {
    this.client.webLogOn();
});
