Create a Search Index Configuration Trailhead fix.

If you're working on the My_kav search index and the final step of the badge is failing when you try to verify the chunk records, especially with a query-related error, try the following steps.

1. Verify the Search Index

First, make sure your search index is ready and that the exact name provided in the badge is used:

Search Index Name: My_kav

Make sure there are no spelling differences or extra spaces.

2. Fix the Data Governance Policy

If you're still getting an error when opening the chunk records in Data Explorer, the issue may be related to the existing Data Governance policy.

Follow these steps:

1. Open the App Launcher.
2. Search for Data Governance and open the app.
3. From the left-hand navigation, select Policies.
4. Find the existing policy named All Data Access Ruleset.
5. Copy the policy name before deleting it.
6. Delete the existing All Data Access Ruleset policy.
7. Create a new policy using the exact same name: 
   All Data Access Ruleset

8. Select Rules and choose the resources to protect.
9. In the Resource dropdown, select Object.
10. In the Action dropdown, select Allow access.
11. Under Take Action On, select All Objects.
12. To apply the policy to users, select Users.
13. Under the second Take Action On dropdown, select All Users.
14. Click Save and Activate.

3. Refresh Data Explorer

After the policy has been saved and activated:

1. Go back to Data Explorer.
2. Refresh the page.
3. Repeat the badge step where you open the chunk records.
4. Try running the same query again.

The chunk records should now be visible, allowing you to complete the verification step.

Why this worked for me

The issue appeared to be related to the existing All Data Access Ruleset policy. Recreating the policy with access allowed for all Objects and all Users, followed by refreshing Data Explorer, allowed the chunk records to be displayed.

Hopefully this helps anyone who gets stuck on the final chunk-record verification step.
