Description of problem:
Catalog affected : icr.io/cpopen/datapower-operator-catalog:1.6.2
opm render icr.io/cpopen/datapower-operator-catalog:1.6.2 -o yaml > catalog.yaml yq 'select(.schema == "olm.channel") | select(.name=="v1.6")' catalog.yaml entries: - name: datapower-operator.v1.6.0 skipRange: '>=1.0.0 <1.6.0' - name: datapower-operator.v1.6.1 replaces: datapower-operator.v1.6.0 skipRange: '>=1.0.0 <1.6.1' - name: datapower-operator.v1.6.2 replaces: datapower-operator.v1.6.1 skipRange: '>=1.0.0 <1.6.2' name: v1.6 package: datapower-operator schema: olm.channel
This have worked fine untill 4.10 resolver changes. Also using both the replaces and skiprange seems to be okay the way it was explained here
https://v0-18-z.olm.operatorframework.io/docs/concepts/olm-architecture/operator-catalog/creating-an-update-graph/#skiprange
How reproducible:
use following subscription, install 1.6.0 and then upgrade to 1.6.2
apiVersion: operators.coreos.com/v1alpha1 kind: Subscription metadata: labels: operators.coreos.com/datapower-operator.openshift-operators: "" name: datapower-operator namespace: openshift-operators spec: channel: v1.6 installPlanApproval: Manual name: datapower-operator source: datapower sourceNamespace: openshift-marketplace startingCSV: datapower-operator.v1.6.0
Error n subscription yaml :

Expected results:
if this upgrade strategy which has worked fine before is still okay, this error should not be there. As per affected catalog maintainer, this seems to affecting reconciling of other resources.
