错误:在dolphinscheduler中运行流程实例时，工作站服务器上发生java.lang.NullPointerException

Question

使用独立部署成功部署了dolphinscheduler。按照工具视频(https://www.bilibili.com/video/BV1d64y1s7eZ)，当我尝试在dolphinscheduler中运行进程实例时，在workerserver和ApiApplicationserver上发生了一些错误。工作器服务器错误图片：https://i.stack.imgur.com/lWQsU.png

Answer 1

请检查您的邮件告警配置，可能是告警参数错误，认证失败。

Answer 2

看起来你只是用外壳运行简单的回显，可能你的环境配置不正确，你可以按照官方文档安装doc
