描述 description

问题
在AEM中激活页面时，激活会失败，并出现以下异常：

javax.servlet.ServletException: java.lang.NullPointerException
at com.day.cq.wcm.core.impl.reference.ActivationReferenceSearchServlet.doGet(ActivationReferenceSearchServlet.java:175)
at org.apache.sling.api.servlets.SlingSafeMethodsServlet.mayService(SlingSafeMethodsServlet.java:269)

环境
AEM 6.x

原因
页面引用的其中一个图像出现属性问题。

导致问题的图像缺少 cq:lastReplicated 属性，而它具有 cq:lastReplicatedBy 和 cq:lastReplicationAction 属性。

指定的消息

javax.servlet.ServletException: java.lang.NullPointerException
at com.day.cq.wcm.core.impl.reference.ActivationReferenceSearchServlet.doGet
at org.apache.sling.api.servlets.SlingSafeMethodsServlet.mayService

识别存在此冲突的所有图像：

code language-none

code language-none
`SELECT * FROM dam:Asset AS parent INNER JOIN nt:base AS child ON ISCHILDNODE(child,parent) WHERE ISDESCENDANTNODE(parent, '/content/dam/journey/') AND child.cq:lastReplicated IS NULL AND child.cq:lastReplicatedBy IS NOT NULL`

SELECT * FROM dam:Asset AS parent INNER JOIN nt:base AS child ON ISCHILDNODE(child,parent) WHERE ISDESCENDANTNODE(parent, '/content/dam/journey/') AND child.cq:lastReplicated IS NULL AND child.cq:lastReplicatedBy IS NOT NULL

标识资产后，检查这些资产是否实际复制。
如果是，添加属性 cq:lastReplicated 具有类型日期并从发布服务器复制日期。
在任一情况下，您都可以删除 cq:lastReplicatedBy 和 cq:lastReplicatedAction 属性，然后再次激活图像。
