Second db connection doesn't receive "save" event.

I currently have two db connections set up:

  1. for the main application
  2. for the utility app that manages some parts differently which cannot be handled by the main application

The issue is that I have set up a post hook on the “save” event to listen to that event with the 2nd application but it’s not working.
The main app creates a new document in the database but the “save” hook does not get executed. May it be due to role restrictions? The 2nd app only has the find and update permissions on the related collection.

Unfortunatly, db.getRole only returns this for the privileges as the result (with the showPrivileges option enabled):
privileges: [ { resource: [Object], actions: [Array] } ]
