Logstash: 6.2.2

Installed `logstash-input-websocket` via `logstash-plugin`

Input:

```auto
input {
  websocket {
    id => "meetup-rsvp-websocket"
    url => "http://stream.meetup.com/2/rsvps"
  }
}

```

Errors:

```auto
[2018-03-06T01:24:15,246][WARN][logstash.inputs.websocket] websocket input client threw exception, restarting {:exception=>#<NoMethodError: undefined method `force_encoding' for nil:NilClass>}`

```

Happens about every second. There is still data flowing, just lots of these exceptions happening. There don't seem to be more logs associated with this error (checked the Logstash logs on `DEBUG`).

Using `ws://` instead of `http://` did not help.
