2026/01/22 16:44:09  [ERROR]  : [Executor] collection error: collect catalog "registry.redhat.io/redhat/redhat-operator-index:v4.20": invalid default channel configuration for package "cluster-logging": the default channel "stable-6.4" was filtered out, a new default channel must be configured for this package 

FIX:

In imageset-config.yaml, change:

    - name: cluster-logging
      channels:
      - name: stable-6.2

by

    - name: cluster-logging
      channels:
      - name: stable-6.4
