VxRail：排定的 VxRail 備份工作失敗，並顯示「NoneType」物件沒有屬性「replace」

目前在 VxRail 版本 7.0.350 上出現此問題，解決方案僅適用於此版本。
在 VxRailBackupRestore.log：

如果您手動執行備份工作：

修改指令檔  /mystic/vxm_backup_restore/common.py 如下所示，再添加兩行。
注意：小心修改，使用空格作為縮進。

def get_primary_datastore(cluster_obj):
    """Get the primary datastore on the specified cluster"""
    if not cluster_obj:
        return None

    if not cluster_obj.datastore:
        return None

    current_vxm_sn = get_vxm_sn()
    for datastore in cluster_obj.datastore:
        if not datastore.vm:
            continue
        for vm in datastore.vm:
            if vm.summary.config.uuid is None:     # new added
                continue                              # new added
            vm_uuid = vm.summary.config.uuid.replace("-", "")
            if vm_uuid in current_vxm_sn:
                return datastore

    return None
