Is there a way using filebeat to find and replace a string in the [message] field of a log entry before sending to Elasticsearch? (similar to mutate and gsub in logstash)

Hi!

Script processor might be the way to go here: [https://www.elastic.co/guide/en/beats/filebeat/master/processor-script.html](https://www.elastic.co/guide/en/beats/filebeat/master/processor-script.html)
