Websocket input client threw expection- No Method error

[Nidhi_Mishra (nidhi)]

The Config file of Logstash for the Websocket Client-

input {
          websocket {
        	codec => "plain"
        	url => "http://localhost:8080/WebsocketHome/"
          }
        }
output {
          elasticsearch {
            hosts => ["http://localhost:9200"]
            index => "websocket"
            #user => "elastic"
            #password => "changeme"
          }
        }

and the following warning comes on the console for logstash:

websocket input client threw exception, restarting {:exception= #<NoMethodError: undefined method 'each' for #<FTW: :Response: 0x ******** >>}

And as for Kibana , the no file is getting uploaded.

I am running into the same exact issue was well

Please find my pipeline below:

input {
    websocket {
      url => "wss://certstream.calidog.io"
       codec => "json"
    }
}
output {
       elasticsearch {
                hosts => [ "localhost:9200" ]
                index => "calidog"
        }
}

Error:
[WARN ] 2018-10-25 17:32:05.483 [[main]<websocket] websocket - websocket input client threw exception, restarting {:exception=>#<NoMethodError: undefined method `each' for #<FTW::Response:0x7279ccb8>>}

**Update:

I added the forward slash / to the end of the url like below and receive hanshake_failure error

input {
websocket {
url => "wss://certstream.calidog.io/"
codec => "json"
}
}

Error:

[2018-10-25T18:52:55,836][WARN ][logstash.inputs.websocket] websocket input client threw exception, restarting {:exception=>#<OpenSSL::SSL::SSLError: Received fatal alert: handshake_failure>}

Alright, I have tried this and it worked for me. I hope it helps and it was truly a pain researching for solution for this problem. It was a little frustrating with visit many posts relating to this issues and most of them are left without an answer. so I really hope this helps you and potentially many other people

  input {
    websocket {
      mode => "client"
      url => "wss://certstream.calidog.io/?param=logstash"
      type => "string"
    }
  }

  output {
    elasticsearch {
      hosts => [ "localhost:9200" ]
      index => "calidog"
    }
    stdout { codec => rubydebug }
  }

so it will complains regardless when the client cannot get data from server but data is still flows.

Happy logstashing!
