Geomesa WPS tubeselect错误

我正在从这个image运行geoserver 2.9.4并且我试图让tubeselect示例工作，因为我需要显示点如何随时间移动 . 我的WPS请求如下：

    </wps:RawDataOutput>
  </wps:ResponseForm>
</wps:Execute>

但是当我执行WPS进程时，我收到以下错误：

<ows:ExceptionText>Unrecognized request type {}</ows:ExceptionText>

我的设置是几何1.3.2，apache accumulo作为DataStore . 我的数据存储区是几何：posiciones

任何的想法？
