blade-desk调用blade-flow提示"请求未授权"

我按照帮助文档，创建请假申请不成功，调试时，发现blade-desk工程的startProcess函数调用blade-flow的startProcessInstanceById请求返回"请求未鉴权"，从日志看这个请求头没有鉴权信息，怎么处理？

blade-desk，LeaveServiceImpl类的startProcess函数，调用startProcessInstanceById，

R result = flowClient.startProcessInstanceById(leave.getProcessDefinitionId(), FlowUtil.getBusinessKey(businessTable, String.valueOf(leave.getId())), variables);

日志输出：
