Summary
When attempting to duplicate an Indicator Match rule from that rule's Details page, the action fails and an error toast is displayed:
Initial toast:

Expanded toast:

Other notes:
- The rule can be duplicated from the rules table on the main Detections page
- This does not appear to affect 7.10; I have only been able to reproduce on
7.11 master/7.12.
