Delete nodes using Rules and VBO Rues and VBO are not working as expected to delete nodes. Can someone tell me what I'm missing? Thank you.

What I have: 


A View with VBO field which successfully selects all nodes of a certain type based on how long ago they were created. (The Preview shows all the desired nodes.)
A Rules Action set which: 



A. Load a list of entity objects from a VBO View. Obviously the chosen View is the View from step 1 above. 

B. Loop through the list of entity objects.

C. Deletes each list item using "Delete entity".


A Rule which runs on cron and has for its only action the above Action Set (and no conditions). 


However, it's not working. I run cron via drush and none of the nodes are deleted. 

I have cleared all caches, recreated each part of the process from scratch (i.e. not cloning anything)... but it's still not working. 

I have also created a Page display in the View (because the Rules Action set uses the Master display) and I can successfully manually delete the nodes with VBO - it's just not working when used in a Rule/Action Set. 

However, the site is already deleting User entities with an identical Views/VBO/Rules/Cron setup. 

Has anyone come across this or have any idea what might be wrong? Thanks.
Here is an "educated" guess:


Your site is configured so that anonymous users are NOT allowed (= do not have the permission) to delete nodes.
Cron (always) runs with user anonymous.


Up to you to confirm if bullet "1." applies, but rest assured that bullet "2." is true (in any Drupal 7 site). So if "1." indeed applies, the answer to your question (= "What am I missing") is that to get this to work you need to grant delete of nodes to anonymous users. I bet it is not going to be what you want to do (I wouldn't ...), but trust me, that is what you're missing.

And BTW, it must be that the userid you used to "successfully manually delete the nodes with VBO" does have the required permission.

To verify if my guess makes sense: (temporary) grant access to the VBO view to anonymous users, logout from your site, and repeat your manual attempt to delete the nodes with that VBO view again (as anonymous user). I bet it will fail with some sort of permission issue. Turn on Rules debugging (within Rules sessings) to get more details about that via the Rules logging messages shown near the top of your screen).
