I have upgraded to 6.7.2 from 6.7.2 of logstash where I am now receiving the following error
Rejecting mapping update to [logstash-2019.05.11] as the final mapping would have more than 1 type: [log4net, doc]"
the config has not changed. Does anyone know why this as occurred and how do I stop the second type being sent through.
You could start by reading this which covers the why, the when, and what your options are. The release notes say there were related changes to the elasticsearch plugin in 6.1.0.
I have tried using a script to change the value of type. I have even tried dropping the type field that is passed from the event and adding a new field for type but I still get the 2 type error.
