Hippocollection:collection not found


Hello guys.
I’ve upgraded a 11.2.1 to 11.2.4 installation because I needed to use the LockManager. All seems to be fine in my local environment, but in other environments I’m facing some strange issues. These environments are setup with separate delivery applications.

Upon start I can see this the logs:
1.01.2019 13:45:13 [http-nio-8080-exec-8] ERROR [org.apache.jackrabbit.core.LazyItemIterator.prefetchNext():153] failed to fetch item 22d06de3-7033-438a-bd6c-ea9d4168a3fb, skipping…
javax.jcr.nodetype.NoSuchNodeTypeException: {http://www.onehippo.org/jcr/hippocollection/nt/1.0}collection

In fact, when looking at the jcr:system/jcr:nodetypes I cannot find that nodetype.

Moreover, the event bus seems to have stopped working, as my post publication handlers doesn’t trigger anymore.
What could be the cause?

Thanks in advance,


hippocollection:collection is from the advanced search plugin for the CMS. Did you recently add or remove this plugin? I would not expect a minor upgrade to have such issues in any case.
