Good Day,
Just updated to 7.10 and while examining the kibana logs I find:
{"type":"log","@timestamp":"2020-11-25T20:37:07Z","tags":["error","plugins","securitySolution","plugins","securitySolution"],"pid":22460,"message":"Bulk Indexing of signals failed: reason: "No mapping found for [@timestamp] in order to sort on" type: "query_shard_exception" name: "Virtual Machine Fingerprinting" id: "cd23d3ba-a8a3-4b1d-9fd0-8946e06b9690" rule id: "5b03c9fb-9945-4d2f-9568-fd690fee3fba" signals index: ".siem-signals-default""}
It appears to being caused by a plugin? Is that a SIEM thing perhaps?
