oc-mirror failed with check the minVersion, maxVersion, and default channel for each invalid package.

Environment

• Red Hat Container Platform 4.x
• Red Hat Quay 3.x

Issue

• oc-mirror failed mirroring of quay-operator in OCP

error: error converting declarative config to include config: invalid index:
├── invalid package "container-security-operator":
│   └── invalid channel "stable-3.8":
│       └── channel must contain at least one bundle
└── invalid package "quay-operator":
    └── invalid channel "stable-3.8":
        └── channel must contain at least one bundle

Resolution

• ImageSetConfiguration declaration was not right. The following ImageSetConfiguration worked fine.

kind: ImageSetConfiguration
apiVersion: mirror.openshift.io/v1alpha2
storageConfig:
  registry:
    imageURL: az01mirror.dachlab.net:8443/ocp-mirror/quaytest
    skipTLS: false
mirror:
  operators:
    - catalog: registry.redhat.io/redhat/redhat-operator-index:v4.11
      packages:
        - name: quay-operator
            minVersion: 3.7.11
            maxVersion: 3.8.0

Root Cause

• ImageSetConfiguration declaration was wrong.

The following snippet of ImageSetConfiguration without min and max version of package did not work.

packages:
        - name: quay-operator
          channels:
            - name: stable-3.7
