Here is the advice I gave you last time:

> If you don't know how to do it, feel free to ask in #logstash channel.

If you still want to ask here, you need to provide informations to help to diagnose such as:

- a sample pipeline which reproduces your problem
- a first correct input content
- the input content that make failing your pipeline
- optionally if any the mapping your defined
- the mapping generated for your index
- if exist, the index templates.
