When I run the command `bin/logstash -f 01-wazuh.conf` two errors pop up and one warning. Although the file is on the specified path, oh well, the most important thing is how to fix the two lower errors?

```

```

Here is the config logstash:

```
input {
  file {
    type => "rails logs"
    path => "/home/users/apps/demo/log/logstash_development.log"
    codec => json {
      charset => "UTF-8"
    }
  }
}

output {
  # Print each event to stdout.
  stdout {
    codec => rubydebug
  }

  elasticsearch {
    # Setting 'embedded' will run a real elasticsearch server inside logstash.
    # This option below saves you from having to run a separate process just
    # for ElasticSearch, so you can get started quicker!
    index => "wazuh-alerts-3.x-%{+YYYY.MM.dd}"
    document_type => "wazuh"

  }
}
```

> Path "/usr/share/logstash/data" must be a writable directory. It is not writable.

Either run Logstash as a user with write access to the directory or change the data directory path using the available settings in logstash.yml or the command-line option.
