%{host} %{message} error logstash

[Alok]

I am trying to put some data from protgres to Elasticsearch through jdbc.

When I execute the command
/bin/logstash -f <FIlename.con f>

the pipeline gets started , the execution reaches to the point where select query is about to be fired and then abruptly the pipeline terminates showing the below error -
%{host} %{message}
%{host} %{message}
%{host} %{message}

Interestingly , this works fine in another machine. Both systems have same version of Java.

This issue is closed. I was not using stdout { codec => json } or rubydebug and hence was thinking its some kind of error.
