Hi all, i am developing logstash input plugin which will scrape data from facebook, but i have problems testing it in logstash, with that plugin, logstash fail to run, **my config** :

```
input { 
    fb-scrape {
       limit => "100"
       page_id => "123456"
       date_file => "dateConfig.conf"
       access_token => "xxxYYYzzz"
    }
}
output {
  stdout { codec => rubydebug }
}

```

**terminal output from logstash:**

ondro@ubuntu:/usr/share/logstash/bin$ sudo ./logstash --log.level trace --config.debug -f /etc/logstash/conf.d/logstash.conf

Problem is probably with code of my plugin, because with stdin input logstash works, but how to find out whats wrong? Should i post code of my plugin as well here?  
Thanks for any answer and for your time
