cannot delete archived applications.

I get this error message:

Waiting for task: 562432571
error: Deleting images
Error: Unhandled Exception: Child Task 562432575 failed: Failed to delete image app-470120:image-1637300 from registry, {"errors":[{"code":"UNKNOWN","message":"unknown error","detail":{"Path":"/docker/registry/v2/repositories/app-470120/_manifests/tags/image-163

Still can't delete my archived applications. Any ideas anyone?

many thanks.

I cleared out the error and was able to remove the application.
