list_volume_qos_histograms doesn't seem to work

• Python 3.10.12
• solidfire-sdk-python 12.3.0.203

According to the docs, volume_ids are optional.

list_volume_stats and list_volume_qos_histograms is supposed to work the same way, but it doesn't.

TypeError: 'int' object is not iterable

It also doesn't work with an array.

Forgot to mention in the case somebody comes across this before it's fixed: the old "invoke" workaround still works fine. {"volume_ids": [1]} has no effect, all volumes' QoS histograms get listed.

sfe.invoke_sfapi("ListVolumeQoSHistograms", parameters={})
