Trailhead challenge-- Bring External Data into the Contact Page Layout
In contact page layout I have added data cloud related list but giving below error, while data model object has correctly mapped

Hi @Smita Arora
This error can occur if the ExternalReservation → Contact relationship is not active/configured correctly.
Please try the following:
- Go to Data Cloud → Data Model → ExternalReservation.
- Open Relationships → Edit.
- Enable Show inactive relationships.
- Check that the Contact ID relationship to Contact/Individual is active.
- Save the relationship and refresh the page.
- Then go back to Setup → Object Manager → Contact → Data Cloud Related List and verify the ExternalReservation related list again.
Also make sure the Data Streams show Success and contain records before testing the related list. The Trailhead module notes that data-stream processing can take some time.
If the issue still occurs, I would recommend creating a fresh Trailhead Data 360 playground and repeating the setup, as similar UNKNOWN_EXCEPTION issues have been reported in this challenge.
If you find this response helpful, please mark it as the Accepted Answer, as it may also help other Trailblazers.
