I try packer build by packer-ansible-windows

And get error when use "source_image_family": "windows-2019-gvlk",

    yandex: fatal: [default]: FAILED! => {"changed": false, "module_version": "9.1.0", "msg": "PowerShell DSC resource DSC_xRemoteFile  failed to execute Set-TargetResource functionality with error message: Invoking web request failed with error. The remote server returned an error: (404) Not Found. ", "reboot_required": false}

  vars:
    uri_exch2016cu12: "https://storage.yandexcloud.net/msft-exchange/ExchangeServer2016-x64-cu12.iso"

https://github.com/yandex-cloud/examples/blob/master/packer-ansible-windows/ansible/exmb_prereq.yml#L5
