get_storage_info_for_blob returns ClientError, TooManyDevicesError

[BillmanH]

Using the method described in this doc, and reviewing the throttle limits here

There is only one single device for this use case no other devices registered in my IoT Hub. I'm using the same devices every time. And I'm only uploading one file at a time (or at least I think I am). However once you get this message you can never use that device connection string again and you must get a new device. Am I missing some kind of disconnect and is there really no way to repair the device once you get this message?

Here is the full source code I'm using for upload:

This notebook shows the framework of the issue:

The above exception was the direct cause of the following exception:
