Getting error while trying to debug chrome cast custom receiver

Question

I am getting an error below while trying to debug the custom receiver.

cast.receiver.logger.setLevelValue(cast.receiver.LoggerLevel.DEBUG);

This is the error when I execute the up statement;

VM213:1 Uncaught TypeError: Cannot read property 'setLevelValue' of undefined at :1:22

How can I deal with this?
