az consumption budget command faulty

Hi

I'm seeing this problem every time I try to run this command to get the details for my subscription -

> az consumption budget list
Command group 'consumption' is in preview and under development. Reference and support levels: https://aka.ms/CLI_refstatus
(422) This operation is not supported in the version specified in the request. Please use version 2019-10-01-preview or later. (Request ID: 8968fd1b-5987-4fc8-842a-69962d47f19f)

The command appears to be calling an out of date API - '2018-01-31' . My CLI version is 2.40.0.

Is this command actually working? If not it would be good if it wasn't available until it is.

Thanks

Cat
