Describe the bug
Backing up an IoTHub instance, after running the script for 2h 30mins we get a KeyError: 'x509Thumbprint' crash .
To Reproduce
In our case it was enough to run az iot hub state export --hub-name prod-hub --state-file state.json.
Expected behavior
The statefile should have been generated without errors.
