Hi all,
i'm using the following configuration in logstash:
```
file {
type => "gzip"
path => "/export/home/elastic/logstash-5.6.1/list.txt"
start_position => "beginning"
codec => gzip_lines
add_field => { "log_type" => "prodvenproxypal" }
```
}
Plugin was installed, but i receive the following error:
