Issue/Introduction

• When navigating to: Operations > Configurations > Notifications, selecting a notification rule, and clicking Edit, the operation fails and displays an Internal Server Error and UI fails to load the edit configuration screen.

  ERROR [ajp-nio-127.0.0.1-#####-exec-###] com. vmware. vcops.ui.action. UtilityAction.execute - JavaScript Error - Msg: Uncaught TypeError: Cannot ad properties of undefined (reading 'args'), Url:https://<AriaOperations_FQDN>/vcf-operations/plug/ops/js/components/ext-overrides.js?version=<AriaOperations_version>, Line: 1930

 

Environment

Aria Operations 8.18.x

Cause

This issue occurs when a notification rule contains references to Object Types associated with management packs that have been uninstalled or are no longer available in the environment

Resolution

To resolve this issue, the corrupted notification rule must be identified, removed, and recreated using valid, currently supported object types.

Step 1: Identify and Export Affected Rules

1. Log in to the VMware Aria Operations UI.

2. From the left menu, navigate to Operations > Configure > Notifications.

3. Locate the notification rule that is triggering the error.

4. Select the rule, click the three dots (Toolbar options), and select Export.

5. Save the resulting .json file to your local machine.

Step 2: Verify Object Types

1. Open the exported .json file in a text editor (e.g., Notepad++, VS Code).

2. Search for fields defining the Object Scope or Resource Types.

3. Cross-reference these object types with the current inventory in Aria Operations. If an object type listed in the JSON belongs to a management pack you recently uninstalled, this is the cause of the failure.

Step 3: Delete and Recreate the Rule

Because the UI prevents editing the corrupted rule, it must be deleted:

1. In the Notifications pane, select the affected notification rule.

2. Click the three dots (Toolbar options) and select Delete.

3. Click Add to create a new notification rule from scratch.

4. Ensure you only select currently available Object Types

5. Save the new rule and verify that you can now edit it without errors.
