该问题的一点背景： 我公司要求从笔记本级别连接到zeppelin web-server并执行一些基本操作，如保存，运行和编辑段落。我还必须使用这些段落创建一些自定义可视化。基础项目在Google Polymer中，我一直使用https://github.com/hph/web-socket/作为我的websocket组件。
我的前端在端口'3000'中运行并与位于=＆gt;的zeppelin websocket服务器通信WS：//本地主机：8080 / WS /
现在问题是，'GET_NOTE'操作正常; 'COMMIT_PARAGRAPH'操作正常。但'RUN_PARAGRAPH'永远不会有效，它只返回=＆gt;状态： “ERROR”
。Zeppelin版试用：0.6.0和0.6.1。 这是我的有效负载和websocket标记：
