download-batch command fails

[vignatov]

Error when trying to download all file from a storage

Describe the bug

We have a bunch of diagnostic information dumped to the storage from our model. The blob name is just a printout of time when it was generated:

These blobs then have to be downloaded and processed on a separate machine. We tried to use the download-batch command, but it fails with the error described below.

Command Name
az storage blob download-batch

Errors:

The command failed with an unexpected error. Here is the traceback:

Hi @vignatov,

2.47.0 is not the latest Azure CLI(2.48.1).

Please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.

Thank you for opening this issue, we will look into it.

BTW, the same error occurs after upgrading Azure CLI to 2.48.1.
