Run multiples pipelines fail

Thx for all it works fine !

For people which could have the same problem, this is my filebeat.yml conf :

filebeat.prospectors:
- type: log
  enabled: true
  paths:
    - /home/log/malwarebytes/*.csv
  fields_under_root: true
  fields:
   filetype: malwarebytes
- type: log
  paths: /home/log/ironport/*.csv
  fields_under_root: true
  fields:
   filetype: ironport

And then, I just merge my two pipelines into only one and I do the distinction into this one like that :

 if [filetype] == "ironport"
 {
  elasticsearch
  {
    hosts => "http://localhost:9200"
    index => "ironport-monitoring"
  }
 }
 else if [filetype] == "malwarebytes"
 {
  elasticsearch
  {
     hosts => "http://localhost:9200"
     index => "malwarebytes-report"

Thx @Badger
