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.
