Your code says `yeild`, not `yield`. But that shoudn't even be necessary, as `new_event_block.call(generated)` should send the new event already: [https://www.elastic.co/guide/en/logstash/current/plugins-filters-ruby.html#\_inline\_ruby\_code](https://www.elastic.co/guide/en/logstash/current/plugins-filters-ruby.html#_inline_ruby_code) (I've done that myself in the past without `yield`)
