Example Using Logging Methods

try {

if(current.u_city.nil()){

  current.u\_city.setValu\(current.u\_attendee.location.city + ", " + current.u\_attendee.location.state\);

}

}

catch(err) {

gs.error("This error occured at runtime: " + err);

}

OUTPUTS: This error occured at runtime: TypeError: Cannot find function setValu in object.

If using logging methods in production, always select the appropiate log type for the event or log message (error, info, warn or debug).
