I am new to kibana, logstash and elasticsearch, i am trying to implement https://github.com/shadow-box/Palo-Alto-Networks-ELK-Stack on my kibana and i am getting the following error when i open the kibana dashboard. Appreciate any help given, thank you.
The exclude.pattern syntax that is being used in the significant_terms aggregation was available in Elasticsearch 2.0 - 5.6.x. It is no longer available in 6.x and greater (looks like you're running 6.x based on the screenshot).
You'll need to update the saved objects for this visualization to use the new syntax (see the doc linked above).
