更新受控文件属性时报错Error: Controlled document has no specified document class

Error Executing Query
Controlled document has no specified document class.
受控信息丢失！

在DCM中点击“受控信息” 报错：class java.lang.NullPointerException


执行如下脚本
create object dcm_extended_sysobject set parent_id='0902055880155f4b',set document_class='ECR_PCN相关表单',set permanent_link=false,set child_id='37020558800178ad',set relation_name='dcm_extended_sysobject'

parent_id：受控文件ID
document_class：在表dcm_document_class中查找相应值
child_id：是执行脚本后生成对象的ID
