I have this exact same issue. Did you find a resolution?

My only guess was that my Registry does not have Defender for Cloud enabled on it. However, I can't figure out how to enable it because it's part of a Development subscription....

Just bumping this again.

I got it working for a time with a Production instance of Defender for Cloud and a production Registry. However, lately, I have had issues with my build pipeline failing to find results even though manually running via PowerShell locally works fine. I am pulling settings from Azure Key Vault in both instances.

It's very frustrating to not be able to troubleshoot this and Defender for Cloud is very opaque in what it displays from the dashboard.
