I am getting the following message when trying to send data to ES.
[2018-03-12T21:32:21,710][WARN ][logstash.outputs.elasticsearch] Could not index event to Elasticsearch......"error"=>{"type"=>"mapper_parsing_exception", "reason"=>"Field name [NAME.ID] cannot contain '.'"}}}
How can I fix this issue?
ES 2.4.1 (not 4.4.0)
LS 5.6.8
