Logstash doesn't work with new data


I made some change in the content of some fields of elasticsearch !
Concretely this corresponds to change the content of some columns in my CSV document and then integrate the new document (in own sense) in the database managed by elasticsearch and finally I launched the logstash command but when I checked my new content I've realized that there's no change ! So I deleted the index to integrate the correct one but now my index won't be integrated and logstash doesn't return any error !!!

What can be the problem ?!

Thank you !
