How to remove fields exist in _source array field using logstash filter

I'm trying to use a logstash filter to remove unwanted fields from the _source field, but the data isn't being sent to ES.

filter {
    mutate {
        remove_field => [ "path", "host","@version","@timestamp","type"]


I think the problem isn't the remove_field directive in this case. It works at this way and it's correct.

Can you add more information about your logstash configuration? The output for example.

Are you receiving data from the input?
