Fatal error when processing CSV file

[code_diva]

I am processing a CSV file with a conf file I have used before together and have not gotten this error in the past on a different server. Passes config test and about 1/4 of the data makes it into Elastic without any issues before this error is thrown. How do I fix it?

What's your config look like? What version are you on? What JVM? What OS?

Thanks.

My config file:
input {
file {
start_position => "beginning"
path => ["/var/tmp/mycsv.CSV"]
}
}
filter {
csv {
separator => ","
autodetect_column_names => true
autogenerate_column_names => true
}

ruby {
code => "
hash = event.to_hash
hash.each do |key,value|
if value.to_s.include? '|' and !key.to_s.match(/message/)
array = value.to_s.split('|')
event.set(key, array)
end
end
"
}
}
output {
stdout { codec => "rubydebug" }
elasticsearch {
"hosts" => "myelastic:9200"
"index" => "grand-csv-test"
"document_type" => "c"
}
}
