The CatalogSource file created by oc-mirror for v2 format is invalid

when I used the file to create CatalogSource, the creation failed and hit error:
[root@preserve-fedora36 cluster-resources]# oc create -f cs-redhat-operator-index-v4-15.yaml 
The CatalogSource "cs-redhat-operator-index-v4-15" is invalid:
