title: Error while trying to send the message over websocket connection in Jmeter | WebSocket Samplers by Peter Doornbosch
body: <p>I am using a plugin (WebSocket Samplers by Peter Doornbosch) to establish the WebSocket connection in JMeter and trying to send the request message over it but receiving below error in logs</p>
  <pre><code>ERROR - eu.luminis.jmeter.wssampler.RequestResponseWebSocketSampler: Unexpected frame type received in sampler 'WebSocket request-response Sampler': Close frame with status code null and close reason 'null'
  </code></pre>
  <p>My test plan consists of &quot;WebSocket Open Connection&quot;, &quot;Web-socket request-response sampler&quot; and &quot;web-socket ping/pong frame filter&quot;. And I feel there is no issue in establishing the connection but something is wrong while sending the request or receiving a response.</p>
  <p>Also, tried checking the logs from the server but didn't find any requests which were sent using JMeter.</p>
  <p>Implemented another available plugin too in Jmeter to test the WebSocket but seeing similar behavior. Any help would be highly appreciated.</p>
