Hi
In logstash output for elasticsearch am using below code and getting

NoMethodError: undefined method `<’ for nil:NilClass>

if ([hour] < 2 ){
elasticsearch{
host =>[10.343.434.343:9200]
index => index -1
}}
} else if ( 5 > [hour] and [hour] >=2 )
{
elasticsearch{
host =>[10.343.434.343:9200]
index => index -2
}
}

That configuration is not even close to being compilable. Please provide a configuration that actually demonstrates the issue.

That said, I would expect that error if you have pipeline.java_execution false and the [hour] field does not exist. (With java_execution true you get a much less informative NPE.)
