I use logstash to stream data from kafka topic to elasticsearch index.  
(Input plugin kafka, output plugin elasticsearch)  
logstash version is 7.8

kafka topic schema include date type.  
example)

```auto
name startDate
type int
logicalType date

```

when I execute logstash pipeline, I got error.

```auto
An unexpected error occurred! {:error=>org.logstash.MissingConverterException: Missing Converter handling for full class name=org.jruby.ext.date.RubyDate, simple name=RubyDate, :backtrace=>["org.logstash.Valuefier.fallbackConvert(Valuefier.java:118)", "org.logstash.Valuefier.convert(Valuefier.java:96)", "org.logstash.ConvertedMap$1.visit(ConvertedMap.java:55)", "org.logstash.ConvertedMap$1.visit(ConvertedMap.java:49)", "org.jruby.RubyHash.visitLimited(RubyHash.java:698)",
...

```

I found code Valuefier.java in elasticsearch/logstash github.  
it seemed like logstash dosent' support Date type, RubyDate.

then what can I do?  
It fails at input stage before filter stage starts.  
so I can't control the field in logstash, which avro schema is date type.

Is there a solution?  
why dosen't logstash support to convert data to date type?

Please let me know if you have a similar problem or solution.  
thank you.
