Read [this](https://discuss.elastic.co/t/getting-illegal-state-exception-error-while-pushing-logs-to-elasticsearch/290029/2) thread to understand what that error is telling you.

You most likely indexed some documents that contain [event][original] (so [event] is an object) since with ECS compatability enabled logstash stores a copy of the [message] field there.

Quickest fix will be to use a different fieldname in your dissect.
