Creating image from blob fails with "Required parameter 'hyperVGeneration' is missing"

[vmwalex]

Creating image from blob fails with "Required parameter 'hyperVGeneration' is missing". The problem started sometime after Apr 9th (same code worked before).

from azure.mgmt.compute import ComputeManagementClient
from azure.common.client_factory import get_client_from_cli_profile
compute_client = get_client_from_cli_profile(ComputeManagementClient)
compute_client.images.create_or_update(
    'myresourcegroup',
    'myimage',
    {
        "location": 'centralus',
        "storage_profile": {
  	    "os_disk": {
                "os_type": "Linux",
                "os_state": "Generalized",
                "blob_uri": 'https://myblobs.blob.core.windows.net/images/myimage.vhd',
                "caching": "ReadWrite"
             }
        }
    })

Error:

Thank you for opening this issue! We are routing it to the appropriate team for follow up.

Hi @vmwalex There was indeed an update to this call, but it was supposed to be backward compatible. I'm contacting right now the "image/disk" team to get the details.

In the meantime, you can use 4.4.0, before the update to this API version.

Thanks,

Hi @vmwalex
I just check with the team, and indeed there was a change of API and the information didn't went well between the RestAPI team and us. I will revert back this change in a 4.6.1 to bring the old behavior as expected following semantic versioning.
Sorry about this :/

I ran into exact same error when trying to create a new azurerm_image from VHD files including a datadisk. Code was working previously, then this week started failing with the "hypervgeneration" missing nonsense.

I eventually found that the Terraform Azure Provider had been updated just two days ago (as per their Changelog), so I pinned the provider version to a few versions prior to the latest, and then all worked again.

Def a problem in the latest v1.34.0. I pinned my code to 1.32.0 and all is ok

Cheers
