What could be wrong with my config. I am getting below error message in logstash.log file
[2017-12-11T19:12:10,130][ERROR][logstash.filters.ruby] Ruby exception occurred: Direct event field references (i.e. event['field']) have been disabled in favor of using event get and set methods (e.g. event.get('field')). Please consult the Logstash 5.0 breaking changes documentation for more details.

Did you look at the Logstash 5.0 breaking changes documentation as the error message suggests?
