      How reproducible:

          Always
          

      Steps to Reproduce:

          1. Install 4.17 cluster and 4.17 oc-mirror
          2. Now use the ImageSetConfig.yaml below and perform mirror2disk using the command below
      [root@bastion-dsal oc-mirror]# cat imageset.yaml
      kind: ImageSetConfiguration
      apiVersion: mirror.openshift.io/v2alpha1
      mirror:
        platform:
          channels:
          - name: stable-4.14
            minVersion: 4.14.20
            maxVersion: 4.14.20
            shortestPath: true
          graph: true
      oc-mirror -c /tmp/imagesetconfig.yaml file:///home/fedora/test-oc-mirror/release-images --v2
          3. Now perform disk2mirror using the command below
          oc-mirror -c /tm/imagesetconfig.yaml --from file:///home/fedora/test-oc-mirror/release-images --v2 --dry-run
          

      Actual results:

          When performing disk2mirror errors are seen as below
      [fedora@preserve-fedora-yinzhou test]$ ./oc-mirror -c /tmp/imageset.yaml --from file:///home/fedora/test-oc-mirror/release-images docker://localhost:5000 --v2 --dest-tls-verify=false --dry-run

      Expected results:

          No errors should be seen when performing disk2mirror
          

      Additional info:

          If not using nestedpaths for file i.e like file:///home/fedora/test-oc-mirror/release-images and just using file://test-oc-mirror things work fine and no error as above is seen.
