小程序消息卡片，移动端客服工作台显示不了卡片封面，而是生产一张小程序二维码图片。

用户咨询航班信息

但是客服工作台收到的消息却是一个二维码

这是我小程序的关联代码

 <button class="clean-button"
                                    session-from="weapp"
                                    send-message-title="{{item.depAirportName}}({{item.depTime}})-{{item.arrAirportName}}({{item.arrTime}})[{{compareReq.cabin =='business'?'商务舱':'头等舱'}}]"
                                    show-message-card="true"
                                    open-type="contact"
                                    send-message-path="/pageParity/pages/parity/parity?mode=1&&dep={{compareReq.dep}}&&arr={{compareReq.arr}}&&date={{compareReq.date}}&&arrDate={{compareReq.arrDate}}&&depC={{compareReq.depC}}&&arrC={{compareReq.arrC}}&&cabin={{compareReq.cabin}}&&adultNum={{compareReq.adultNum}}&&childNum={{compareReq.childNum}}&&leaveCity={{leaveCity}}&&arriveCity={{arriveCity}}&&civil={{compareReq.civil}}"
                                    bindcontact="handleContact"
                                    plain>
