Pipe Plugin Not Working on Windows

Elastic Stack Logstash
1

I'm trying to execute the Logstash-output-pipe plugin, but I can't get it to work with even simplest configuration. I'm executing this command:

bin\logstash.bat --path.settings /I:/logstash-5.2.2/config -l logs -f pipetest.conf

... and getting this output on the console:

Sending Logstash's logs to logs which is now configured via log4j2.properties

Here is my Logstash config file:

input {
    heartbeat {
        message => "sequence"
        interval => 10
        type => "heartbeat"
    }
}
output {
    pipe {
        command => "echo hello"
    }
    stdout {
        codec => rubydebug
    }
}

I'm running Logstash version 5.2.2, Logstash-output-pipe plugin version 3.0.2 on Windows 7 Enterprise (64 bit), Service Pack 1.

Any help you would be appreciated.

Wow. Two days and still no replies. Do I get bonus points for stumping the Logstash community?

I've given up on the pipe plugin and switched to the exec plugin.
