Apologies, here is what elastic search returned:
HTTP/1.1 200 OK
content-type: application/json; charset=UTF-8
content-encoding: gzip
content-length: 183
{"took":0,"ingest_took":1,"errors":false,"items":[{"create":{"_index":"filebeat-7.5.2","_type":"_doc","_id":"auto-generated","_version":-4,"result":"noop","_shards":{"total":0,"successful":0,"failed":0},"status":200}}]}
Also, I have posted this request in the elastic search section as well. They are looking at the pipeline, and I originally thought this related to the pipeline, but the system module uses its own pipline, and it has the same issue. I'm wondering if this is related to the index itself, or something at that level? My elastic search post is at:
