Mantainerr goes down whenever I try to process or reset overlays #2824

Description

@michellichand

Describe the bug
Every time I try to hit the 'run now' or 'reset all overlays' button in the overlays system, my Mantainerr immediately goes to a 502 error and needs to be restarted. I've tried resetting every setting and it still keeps bugging out whenever I try to use the overlays system.

To Reproduce
Steps to reproduce the behavior:

  1. Go to 'Overlays'
  2. Click on 'Run Now' or Reset All Overlays
  3. 'Failed to process overlays' appears
  4. Mantainerr goes 502

Expected behavior
For the overlays to update with the collections, as they did once and then never again.
