Additional Context

[msftbot]

Thanks for submitting an issue, @mheskandari. I noticed your issue contains the following error:

ImportError: cannot import name 'c_uamqp' from partially initialized module 'uamqp'
which can often be solved quickly by either:

• Updating your installed version of the azure-iot extension:
  az extension update --name azure-iot
• Performing a repair of the uamqp dependency:
  az iot hub monitor-events --hub-name {} --device-id {} --repair

Please try these two resolution methods and see if that helps resolve your issue.

Same issue with cloud shell 2.40 and iot extension 0.17.1.

Isse for uamqp 1.2.

@aleschmidt93 have you tried the mitigation posted by the msftbot namely using --repair to re-install uamqp?

[aleschmidt93]

@digimaun Yes, but without any effect. I also deleted the cloud shell storage and created a new one from stretch.
I also opened a case in azure but the support only "escalated this issue to the iot hub team for further investigation" 12 days ago...

@aleschmidt93 this issue was resolved via support request right? Looking to close the issue.
