"Deploy and monitor a model in Azure Machine Learning" deploy-prod fails at "Deploy model to managed online endpoint"

Following Deploy and monitor a model in Azure Machine Learning, "/deploy-prod" fails.

After commenting "/deploy-prod", it is supposed to create an endpoint and deploy to it.

The GitHub action fails at the "Deploy model to managed online endpoint" step with the following error:

Run python src/deploy_to_online_endpoint.py \
Traceback (most recent call last):

  File "/opt/hostedtoolcache/Python/3.10.21/x64/lib/python3.10/site-packages/azure/core/polling/base_polling.py", line 950, in run

azure.core.polling.base_polling.OperationFailed: Operation failed or canceled

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

Error: Process completed with exit code 1.

Start with the deploy-prod GitHub Action and src/deploy_to_online_endpoint.py, especially ensure_endpoint at line 57 and the call at line 100. Reproduce the managed online endpoint deployment and inspect the Azure operation behind the SubscriptionNotRegistered error. Done means the action completes the deployment step successfully.
