There are lots of Freemarker errors in my catalina.out log regarding null lastThumbnailModification properties.
I have found a fix in Jira and Github. The file is mentioned in my error messages:
2021-05-19 15:43:28,969 ERROR [freemarker.runtime] [http-nio-127.0.0.1-8080-exec-5] Error executing FreeMarker template
FreeMarker template error:
The following has evaluated to null or missing:
==> node.properties.lastThumbnailModification [in template "org/alfresco/slingshot/documentlibrary/item.lib.ftl" at line 60, column 14]
However, I can't find the file in the downloaded 6.2 CE source code.
