It is working in the logstash version 5.6 . But not working in 6.3.2 It seems the input can not including two codec parameters . When I delete any one codecs. It is working. How to use both codec in logstash 6.3?

==================================

the input info like this .

input {  
kafka {  
bootstrap\_servers =\> "localhost:9092"  
topics =\> ["pglog","oshistory"]  
codec =\> "json"  
consumer\_threads =\> 2  
decorate\_events =\> true  
type =\> "pglog"  
codec =\> multiline {  
pattern =\> "^\d{4}-\d{1,2}-\d{1,2}"  
negate =\> true  
what =\> previous  
}  
}  
}

For any input plugin, you can only specify a single codec, and you have specified `json` and `multiline`. In this case you may need to keep the multiline codec and use a json filter instead of the codec.
