Send logstash events to log file problem

[dyl (bus)]

Hey,

I use logstash to parse filebeat events and then send these logs to a .txt file

This is my pipeline :

input
{
  beats
  {
    port => 5044
  }
}
filter
{
  grok
  {
    match => { "message" => [ "%{WORD:TYPE};%{DATA:ID1};%{NUMBER:ID2};%{GREEDYDATA:DESCRIPTION}" ] }
  }
  if ([DESCRIPTION] =~ "CODE")
  {
    grok
    {
      match => { "DESCRIPTION" => [ "%{NUMBER:CODE_RETOUR}" ] }
    }
  }
  if ([ID2] == "000003")
  {
    grok
    {
      match => { "DESCRIPTION" => [ "%{DATA:TEST}/%{WORD:NOM_BATCH}-%{BASE16NUM:DATE_BATCH}-%{GREEDYDATA:reste}" ] }
    }
  }
  if ([TYPE] == "INFO")
  {
    if ([ID2] != "000003" and [ID2] != "000005")
    {
      if ([DESCRIPTION] !~ "info BDD" and [DESCRIPTION] !~ "CODE RETOUR")
      {
        drop { }
      }
    }
  }
  date
  {
    match => [ "DATE_BATCH", "yyyyMMdd" ]
  }
}
output
{
# elasticsearch
# {
#   hosts => "http://localhost:9200"
#   index => "gestapplicationna"
# }
    file 
    {
        path => "./test-%{+YYYY-MM-dd}.txt"
        codec => {
          line {
            format => "%{DESCRIPTION}"
          }
       }
    }
}

I want to have only the "DESCRIPTION" field in the created log file but my output section doesn't work. This is the error msg when i try to --config.test_and_exit

[FATAL] 2018-06-14 13:53:13.873 [LogStash::Runner] runner - The given configuration is invalid. Reason: Expected one of #, => at line 53, column 16 (byte 967) after output

#   index => "gestapplicationna"
# }
    file {
        path => "./test-%{+YYYY-MM-dd}.txt"
        codec => {
          line
[ERROR] 2018-06-14 13:53:13.877 [LogStash::Runner] Logstash - java.lang.IllegalStateException: org.jruby.exceptions.RaiseException: (SystemExit) exit

Can somebody help me ?

SOLVED, correct syntax :

file {
            codec => line {
                    format => "%{[DESCRIPTION]}"
            }
            path => "./test-%{+YYYY-MM-dd}.txt"
    }
