new-extension-manifest only supports classic storage accounts

[arthfl]

Creating a new extension manifest fails if one doesn't use a 'classic' storage-account.

ARM storage accounts just don't seem to work. And it fails with a kinda non-descriptive error message:
FATA[0001] Could not fetch keys for storage account. Make sure it is in publisher subscription. Error: Error response from Azure. Code: ResourceNotFound, Message: The storage account '<redacted>' was not found.

Would be great if ARM accounts would be supported too. And at least the error message should get updated.

Sorry, I completely missed this issue. 😞

This tool is completely based on the old Azure APIs, and we haven't yet bridged it to the new world. That is coming, but in the interim I am stuck with classic storage accounts. I can improve the error message to better state that you need a classic storage account.
