crunchy postgres operator backup to azure blob fails - postgres-operator

Question

I want to backup the database into azure blob, but failed.
My configuration is as follows
apiVersion: postgres-operator.crunchydata.com/v1beta1
kind: PostgresCluster
metadata:
name: hippo-azure
spec:
image: registry.developers.crunchydata.com/crunchydata/crunchy-postgres:ubi8-14.6-2
postgresVersion: 14
instances:
- dataVolumeClaimSpec:
accessModes:
- "ReadWriteOnce"
resources:
requests:
storage: 32Gi
backups:
pgbackrest:
image: registry.developers.crunchydata.com/crunchydata/crunchy-pgbackrest:ubi8-2.41-2
configuration:
- secret:
name: pgo-azure-creds
global:
repo2-path: /pgbackrest/repo2
repos:
- name: repo1
volume:
volumeClaimSpec:
accessModes:

resources:
requests:
storage: 32Gi
- name: repo2
azure:
container: "pgo"
patroni:
dynamicConfiguration:
postgresql:
pg_hba:
- "host all all 0.0.0.0/0 trust"
- "host all postgres 127.0.0.1/32 md5"
users:
- name: qixin
databases:
- iot
- lowcode
options: "SUPERUSER"
service:
type: LoadBalancer
My storage account name is pgobackup, container name is pgo.
The content of azure.conf is as follows.
[global]
repo2-azure-account=pgobackup
repo2-azure-key=aXdafScEP28el......JpkYa28nh5V+AStNtZ5Lg==
But there are no files on the blob
Also I executed the following command for a one time backup
kubectl annotate -n postgres-operator postgrescluster hippo-azure postgres-operator.crunchydata.com/pgbackrest-backup="$( date '+%F_%H:%M:%S' )" --overwrite=true
I also tried scheduled backups, but that also failed
- name: repo2
schedules:
full: "18 * * * *"
differential: "0 1 * * 1-6"
azure:
container: "pgo"
Taken from the official documentation.
The official document says that cronjob will be created, but no Job or Cronjob is created.
Can anyone give me some advice?
Thx！
