Minimal steps to reproduce

Edit predocs.ps1 add an --storagekey but the function upload_blobs will fail with: "Unsopported key" It is mandatory to use that type of key, because the normal user needs 2FA. The standard code will not work. You need to add the --storagekey but it does not work.

I edited upload_blobs blob_service = BlobServiceClient(account_url=f"https://{args.storageaccount}.blob.core.windows.net", credential="mykey")

and it works. Can you try using --storagekey and see if it works? Cheers!
