@rohrerb can you rerun the command with the --debug flag and post the full output (it will include all sub commands and their output)?

@rohrerb It looks like the image you're trying to copy isn't a managed one since it's based on a vhd. right?
The extension is able to work with managed images only, and the error is a result of checking that which I'll fix.

[rohrerb]

@tamirkamara

Pretty sure its a managed image. The image was generated using this command.

az image create -g $rg -n $imageName --os-type Linux --source https://$storname.blob.core.$vhdblobendpointname.net/disks/$vhdblobname

[rohrerb]

Thoughts @tamirkamara?

[tamirkamara]

Updated issue: the extension doesn't support copying images backed by a vhd disk stored as blob.
It will be added soon.
