I am using logstash 2.3.4 - the configuration worked for previous inputs in file, some input is now crashing it. How to find the error log line?

Please see below filter clause in config file,
filter {

}

Same issue here also for me. I'm using 2.4.1 version of logstash. Issue is with event\_id condition in filter section(I'm taking even\_id as integer). It seems there is an issue with mutate. It is working fine in output section on same event\_id field
