Hi @here ,

I'm getting below error while loading data From mongodb.

`MongoDB Input threw an exception, restarting {:exception=>org.logstash.MissingConverterException: Missing Converter handling for full class name=org.jruby.gen.RubyObject3, simple name=RubyObject3}.`

```auto
    input {

  mongodb {
    uri => ['mongodb://X.X.X.X:27017/platform_production']
    placeholder_db_dir => '/home/ubuntu/test'
    placeholder_db_name => 'platform_production.ap_user_stayed_time_test.db'
# collection => 'ap_user_stayed_time_1589455272971'
    collection => 'ap_user_stayed_time_test'
    batch_size => 500000
    generateId => 'true'
    parse_method => 'simple'
    }

     }

    filter {

    }

     output {
        stdout {
                codec => rubydebug
               }
        elasticsearch {
        action => 'index'
        hosts => ['X.X.X.X:9200']
        index => 'demo-test-1'
              }
