Cannot enforce policies and data protection rules in Watson Query

Policies and data protection rules are not enforced in Watson Query.

Symptoms

You enabled policy enforcement but policies and data protection rules are not being enforced in Watson Query.

To solve this issue, follow these steps.

Click Catalogs > All catalogs.
Select your catalog and click Browse Assets.
Open the Watson™ Query connection asset and select the Asset tab.
Edit the connection by pressing Click here to edit connection.
Check the connection details to ensure that the Instance ID field is correctly specified and does not contain any blank spaces.
Check that your virtual object is published to a governed catalog and that your rules apply to the corresponding virtual data asset in the catalog.
Assets that are added by using the Data discovery option, and that are tagged as an info_asset are not supported. Ensure that the asset is created from the Watson Query connection type by selecting the data asset in the catalog and clicking Activities > Created from.
If you find an error in the Instance ID field, re-create all data assets that you added by using the Watson Query connection.

After you re-create these data assets, policies and data protection rules are properly enforced in Watson Query.
