I'm having an issues with Logstash 7.2.1 where conditional statements within the output module are being ignored.
Example, I made up `[blahblahblah]`, so it is empty.
```auto
output {
elasticsearch {
id => "output_elasticsearch_prod"
hosts => ["http://${ES_1}", "http://${ES_2}", "http://${ES_3}" , "http://${ES_4}" , "http://${ES_5}", "http://${ES_6}"]
index => "flow_prod"
template => "${ELASTIFLOW_TEMPLATE_PATH:/home/udocker/flowproc/elastiflow/templates}/flow.template.json"
template_name => "flow"
template_overwrite => "true"
}
if [blahblahblah] {
elasticsearch {
id => "output_elasticsearch_remote"
hosts => ["http://${ES_REMOTE_1}", "http://${ES_REMOTE_2}", "http://${ES_REMOTE_3}" , "http://${ES_REMOTE_4}" , "http://${ES_REMOTE_5}", "http://${ES_REMOTE_6}"]
index => "flow_remote"
template => "${ELASTIFLOW_TEMPLATE_PATH:/home/udocker/flowproc/elastiflow/templates}/flow.remote.template.json"
template_name => "flow_remote"
template_overwrite => "true"
}
}
}
```
However I still get this error when logstash starts
```auto

```
I've tried several different combinations of this with no luck. Is there something I missed or am doing wrong? The docs suggest this should work.

An elasticsearch output establishes a connection during startup, it is not initialized when an event that would use it arrives.
