## Summary
**Current behavior:**
- **Scenario 1:** User is in the exceptions viewer flow, they select to edit an exception item, but the list the item is associated with has since been deleted (let's say by another user) - a user is able to open modal to edit exception item and on save, an error toaster shows but no information is given to the user to indicate the issue.
- **Scenario 2:** User exports rules from space 'X' and imports into space 'Y'. The exception lists associated with their newly imported rules do not exist in space 'Y' - a user goes to add an exception item and gets a modal with an error, unable to add any exceptions.
- **Workaround:** current workaround exists only via API - user would need to remove the exception list from their rule via API
**New behavior:**
- **Scenario 1:** User is still able to oped edit modal, but on save they see an error explaining that the associated exception list does not exist and prompts them to remove the exception list --> now they're able to add exceptions to their rule
- **Scenario 2:** User navigates to exceptions after importing their rule, tries to add exception, modal pops up with error informing them that they need to remove association to missing exception list, button prompts them to do so --> now can continue adding exceptions to rule
