No UserTaskView object available for `User Task`, and, an error occured during user assignment.
I followed the academy sample “Build a Powerful Workflow”. I started one workflow about “onboarding” as HR. But I can not assign the user task to “manager”. When pressed the button “Assign to me”, it popups one windows with the message as below: "An error occured during user assignment. Please contact your system administrator". The log details as below: our system administrator". 查看后台的错误日志信息是：No UserTaskView object available for `User Task`. Please check if the event microflows have been configured in the App Settings. I checked the app setting, but did find the setting related to microflow. I have no ideas how to fix it.
