Here, the discord server is down ("Response: Service Unavailable") and throws an exception.

our code, this.client.login(gConfig.discord_bot_token), while wrapped in a try/catch, is async and returns a Promise which I'm not handling exceptions on it.

fix:

            this.client.login(gConfig.discord_bot_token)
                .catch(e => {
                    console.log(`Discord unable to log in ${e}`);
                });
