尝试设置目标时出现WLST Bean错误

Question

我试图通过使用WLST运行python代码来创建一个工作管理器。在我的python代码中，当尝试使用cmo.ADDDTARGET公司（bean），它抛出以下错误：

======= Creating a WorkManager name for WM_AgreementOps11 =======

MBean type WorkManager with name WM_AgreementOps11 has been created successfully.

No stack trace available. This Exception occurred at Mon Feb 04 13:13:51 IST 2019. javax.management.AttributeNotFoundException: com.bea:Name=WM_AgreementOps11,SelfTuning=DefaultDomain,Type=WorkManager:SelfTuning Traceback (most recent call last): File "C:\Oracle\Middleware\Oracle_Home\wlserver\server\bin\WorkManagerSetUp.py", line 70, in main cmo.addTarget(bean) java.lang.IllegalArgumentException: java.lang.IllegalArgumentException: A non-null value expected
