Mirroring all the Quay repository tags when the latest tag is missing, results in "Last Sync Failed" error

Issue

• The mirroring feature is enabled, but the mirroring status returns Last Sync Failed error and the repository has not been mirrored.

• In quay mirror pod logs there is no error log, just these messages:
