This was due to NXP-21334 and the fact that the subscribed documents were fetched in an UnrestrictedSessionRunner: once the unrestricted session was closed, trying to get a property from a data model that hadn't been loaded would throw this exception.

The solution is to detach the documents within the unrestricted code.
Note that NXP-22078 would allow more fluent calls involving DocumentModel#detach(boolean loadAll).

Ideally, we should stop using adapters manipulating the whole document, and just fetch the property that we are interested in, here notif:notifications. Generally speaking, the adapter pattern doesn't work well with unrestricted stuff.
