Hi,

Using logstash 6.7, I'm switching from daily rotated indices to ILM, and am seeing an error when trying to template the ILM settings.

Error

```auto
java.net.URISyntaxException: Malformed escape pair at index 0: %{dest}-6.7.1

```

Config

```auto
input {
  stdin { }
}

filter {
  mutate {
    add_field => { "dest" => "stdout" }
  }
}

output {
  elasticsearch {
    hosts => ["${ELASTICSEARCH_HOST:elasticsearch}:${ELASTICSEARCH_PORT:9200}"]
    user => "${ELASTICSEARCH_USERNAME:}"
    password => "${ELASTICSEARCH_PASSWORD:}"
    ....
    ilm_enabled => "true"
    ilm_rollover_alias => "%{dest}-${LOGSTASH_VERSION:6.X}"
    ilm_pattern => "000001"
    ilm_policy => "%{dest}-${LOGSTASH_VERSION:6.X}"
    manage_template => false
  }
}

```

Previously I had

```auto
...
    index => "%{dest}-${LOGSTASH_VERSION:6.X}-%{+YYYY.MM.dd}"
...

```

Are the ilm settings (such as ilm\_rollover\_alias) not allowed to use variables?

Thanks,  
Justin

Bumping this. Can anyone confirm or deny this?

Thanks, Justin
