2020-05-04 23:07:05,044 ERROR [http-nio-8080-exec-13] [atlassian.confluence.servlet.ConfluenceServletDispatcher] sendError Could not execute action -- url: /pages/viewpage.action | traceId: 1273a70858101de8 | userName: admin | referer: http://localhost:8090/login.action?os_destination=%2Fpages%2Fviewpage.action%3BRelease%2BNote%2BCreation%2BStandards%2Band%2BGuidelines&permissionViolation=true java.lang.RuntimeException: Error rendering template for decorator root at com.atlassian.confluence.setup.velocity.ApplyDecoratorDirective.render(ApplyDecoratorDirective.java:162) . Caused by: org.hibernate.HibernateException: Unable to resolve owner of loading collection [[com.atlassian.confluence.core.ContentEntityObject.contentProperties#152548091]] for second level caching at org.hibernate.engine.loading.internal.CollectionLoadContext.addCollectionToCache(CollectionLoadContext.java:321)
In some cases the error can happen on some other actions in Confluence as well. Though, as long as the cause of the error is the same we can proceed with the resolution here.
The actual error is unable to load an element of ID 152548091 from cache. This ID is seen in the logs.
Try clearing the cache of Confluence, to force a refresh.
- General Configuration > Cache Management
- Select Flush all at the bottom of the page
If the issue isn't resolved by flushing cache, then querying the database for the relevant ID or reindexing the system will be next steps.
