hi,

here is a tail of log

[2020-03-24T10:41:35,144][WARN][logstash.inputs.websocket][main] websocket input client threw exception, restarting {:exception=\>#\<NoMethodError: undefined method `each' for #FTW::Response:0x4b712701\>}

here is the input part of config:

input {

websocket {

#id =\> "CertStream"

url =\> "ws://certstream.calidog.io/?param=Logstash"

type =\> "plain"

mode =\> "client"

}

That looks similar to this [issue](https://github.com/logstash-plugins/logstash-input-websocket/issues/3), although the current version of the code [does test](https://github.com/logstash-plugins/logstash-input-websocket/blob/242fef09204a015dcddcc8a9a5d01cdf43a3261e/lib/logstash/inputs/websocket.rb#L73) whether it has an FTW::WebSocket or an FTW::Response before calling .each, so I would not expect the current code to hit this.
