Nmstate operator was added to the ImageSetConfiguration from an existent mirror configuration file over a disconnected registry. The operator was added from Openshift but it is failing because a missing image:

From the oc mirror mappings resultant file, we see that the file oc mirror obtains has a different digest than the one the operator needs:

registry.redhat.io/openshift4/kubernetes-nmstate-operator-bundle@sha256:5b75b5300f2d730fb19136668cf887d83b37435e87b8320aaa5e8bba8c9cd784=registry.example.com/openshift4/kubernetes-nmstate-operator-bundle:d54d2079


The version from oc mirror we are using is the following:

sh-4.4$ oc-mirror version

    1. Use the above ImageSetConfiguration.
    2. oc-mirror using the config file.
    3. Wait for it to finish.
    

The kubernetes-nmstate-operator-bundle digest is not the one expected.    

   It should obtain the cefdefeded416905fc37d33b54ab7862e01a38598c3c366e30cc2acda9a65075 digest, but it gets the 5b75b5300f2d730fb19136668cf887d83b37435e87b8320aaa5e8bba8c9cd784 digest instead.
