Hi, I'm getting this error when I'm running my logstash pipeline. Is it because I have no valid ssl cert?
Here's my conf
```auto
filter {
elasticsearch {
ssl => false
hosts => ["localhost:9200"]
user => "username"
password => "password"
index => "myindex"
query => "Status:started"
}
}
output {
stdout { codec => rubydebug }
}
```
Here's the error
```auto
