Hi,
Logstash log files are being filled up with indexing errors for filebeat:
[2020-11-12T09:06:02,844][WARN ][logstash.outputs.elasticsearch][main][28a01e4629fbbc3006822900269029f08bd4f371d6be029377ac4944518e3137] Could not index event to Elasticsearch. {:status=>400, :action=>["index", {:_id=>nil, :_index=>"filebeat-2020.11.12", :routing=>nil, :_type=>"_doc"}, #<LogStash::Event:0x19dc9f8>], :response=>{"index"=>{"_index"=>"filebeat-2020.11.12", "_type"=>"_doc", "_id"=>nil, "status"=>400, "error"=>{"type"=>"illegal_argument_exception", "reason"=>"only write ops with an op_type of create are allowed in data streams"}}}}
Any thoughts as to what is causing this? I can't see that it is related to setting up TLS/HTTPS connections for Kibana/Elastic/Logstash
