Hi, I am trying to use the logstash-output-kafka

**////My codes  
input {  
stdin {}  
}**

**output {  
kafka {  
topic\_id =\> "mytopic"  
bootstrap\_server =\> ":9092"  
}  
}**

However, when executing this configuration, I am getting this error:

**//////Output  
[ERROR][logstash.agent] Failed to execute action {:action=\>LogStash::PipelineAction::Create/pipeline\_id:main, :exception=\>"LogStash::ConfigurationError", :message=\>"Something is wrong with your configuration."**

I tried to change ":9092" to "localhost:9092", but that also fails to connect to kafka. Only when I remove the bootstrap\_server configuration (which then defaults to localhost:9092) then the kafka connection seems to be established.

Is there something wrong with the bootstrap\_server configuration of the kafka output plugin? i am using logstash v6.4.1, logstash-output-kafka v7.1.3

It's bootstrap\_server **s** , not bootstrap\_server.
