I am kinda sure this is a bug! Because if I just use ` logstash-input-jdbc` without using sqlite plugin I can import my sqlite data successfully!

Someone opened an issue at [Logstash with sqllite3 problem · Issue #9788 · elastic/logstash · GitHub](https://github.com/elastic/logstash/issues/9788) but it was closed.  
Someone asked a similar question here [Sqlite input plugin not working - #4 by Badger](https://discuss.elastic.co/t/sqlite-input-plugin-not-working/143073/4) but no one answered.

I said a "similar" question b/c I am not sure it is exactly the same as mine. I check sqlite.rb:160

it is ` event = LogStash::Event.new("host" =&gt; @host, "db" =&gt; @db)`

So why LogStash::Event.new failed ?

BTW, it uses `sqlite-jdbc-3.20.1.jar`
