Velero Backup not working for Azure AKS

[faizanbashir]

What steps did you take and what happened:
I am trying to install Velero to take backups for our AKS cluster, but it is failing with the errors. I have created a Storage account container to store the backups from velero.

Installation Command:

helm upgrade --install \
    velero \
    vmware-tanzu/velero \
    --namespace velero \
    --create-namespace \
    --set-file credentials.secretContents.cloud=velerobackup \
    --set fullnameOverride=velero \
    --set image.repository=docker.io/velero/velero \
    --set "configuration.backupStorageLocation[0].config.region=eastus" \
    --set "configuration.backupStorageLocation[0].bucket=akspsrusclusterbacup" \
    --set "configuration.backupStorageLocation[0].provider=Azure" \
    --set "configuration.backupStorageLocation[0].config.storageAccount=akspsrusclusterbacup" \
    --set "configuration.backupStorageLocation[0].config.storageAccountURI=https://akspsrusclusterbacup.blob.core.windows.net \
    --set "configuration.backupStorageLocation[0].config.storageAccountKeyEnvVar=" \
    --set "initContainers[0].name=velero-plugin-for-azure" \
    --set "initContainers[0].image=docker.io/velero/velero-plugin-for-microsoft-azure:v1.9.2" \
    --set "initContainers[0].volumeMounts[0].mountPath=/target" \
    --set "initContainers[0].volumeMounts[0].name=plugins" \
    --set snapshotsEnabled=false \
    --set credentials.useSecret=true \
    --set kubectl.image.repository=docker.io/bitnami/kubectl \
    --values schedules.yaml

What did you expect to happen:
The velero backup should work and write the backups to the storage account container designated for it.

The output of the following commands will help us better understand what's going on:
