I am sending log data to elastic search directly using filebeat 7.10.
I want to drop some fields of doc using drop_fields processors before sending to ES. Filebeat is dropping some fields placed in drop_fields conf but not all. Filebeat throwing following error:
DEBUG [processors] processing/processors.go:128 Fail to apply processor client{drop_fields={"Fields":["agent","host","log","input","ecs"],"IgnoreMissing":false}}: failed to drop field [agent]: key not found; failed to drop field [host]: key not found; failed to drop field [ecs]: key not found
