Error finding remote layer for mongodb-enterprise image when pushing archive to registry. The strange behaviour is seen when mirroring below imageset-config. Please note that this issue appears when pushing to registry after mirroring the images to tar archives first.

kind: ImageSetConfiguration
apiVersion: mirror.openshift.io/v1alpha2

The below error is seen:
error: error occurred during image processing: error finding remote layer "sha256:24bab87b81ab2c2c662f106f59f25a2ed6bd09533f43cf13a780644ebdf34e9a": layer "sha256:24bab87b81ab2c2c662f106f59f25a2ed6bd09533f43cf13a780644ebdf34e9a" is not present in the archive

Removing mongodb-enterprise from the imageset-config helps complete the mirroring without error.

I had opened https://issues.redhat.com/browse/ISVISSUE-515 to find issues with image however after more testing it was found that changing some parts of imageset-config file helps complete mirroring even when including mongodb-enterprise in the file.

For example below imagesetconfig files work:

kind: ImageSetConfiguration
apiVersion: mirror.openshift.io/v1alpha2
storageConfig:
  local:
    path: /home/ec2-user/mirror/metadata/operators-4-12
mirror:
  operators:
  - catalog: registry.redhat.io/redhat/certified-operator-index:v4.12
    packages:
    - name: crunchy-postgres-operator
    - name: gpu-operator-certified
    - name: conjur-follower-operator
    - name: mongodb-enterprise


kind: ImageSetConfiguration
apiVersion: mirror.openshift.io/v1alpha2
storageConfig:
  local:
    path: /home/ec2-user/op-mirror/metadata/operators-4-12
mirror:
  operators:
  - catalog: registry.redhat.io/redhat/redhat-operator-index:v4.12
    packages:
    - name: openshift-gitops-operator
    - name: quay-operator
      channels:
      - name: stable-3.9
      - name: stable-3.10
    - name: rhacs-operator
      channels:
      - name: stable
    - name: web-terminal
  - catalog: registry.redhat.io/redhat/certified-operator-index:v4.12
    packages:
    - name: crunchy-postgres-operator
    - name: gpu-operator-certified
    - name: conjur-follower-operator
    - name: mongodb-enterprise

Please investigate this behaviour for issues with oc-mirror.

    1. Mirror images to tar archive using the first imageset-config provided.
    2. Push the archive to registry.
    3. Error appears
    4. Remove mongodb-enterprise from the imageset-config and try again. Issue is not reproduced.
    5. Perform the same for other 2 imageset-config with mongodb-enterprise included in them. Issue is not reproduced.
    

Strange failure with mongodb-enterprise image not found in archive.
    

Mirroring should succeed.
