Hello,
I am getting an error message "field name cannot be an empty string" for a number of documents coming into logstash. I am attempting to remove the null fields with a mutate filter:
mutate { remove_field => [ "[]" ] }
But I am getting an error:
{:exception=>"Invalid FieldReference: []
"}
Is there a specific way to refer to a null field name so I can remove it (or rename it) or is there another method to resolve?
