The lines with problem are

azure-cli/src/azure-cli-core/azure/cli/core/_profile.py

Lines 275 to 276 in 80c7bc7

	if hasattr(s, 'managed_by_tenants'):
	subscription_dict[_MANAGED_BY_TENANTS] = [{_TENANT_ID: t.tenant_id} for t in s.managed_by_tenants]

This is a known issue of the resources Resource Provider: Azure/azure-rest-api-specs#9567.

Solution: Please select the correct profile with az cloud set --name xxx --profile xxx.

Meanwhile, I will try to make the code of Azure CLI more robust on this kind of server issue.

Hi,

Just to confirm it was an issue with using the incorrect API version profile. It would definitely be great if the Azure CLI was able to give more detailed error messages to indicate that it was an issue with API versions.

Thanks for the help,

Matt

Thanks for the advice. However, this is not really Azure CLI's fault.

Just to confirm it was an issue with using the incorrect API version profile. It would definitely be great if the Azure CLI was able to give more detailed error messages to indicate that it was an issue with API versions.

If 2019-06-01 is not supported by Azure Stack, the API should return an error, instead of returning the incorrect response which doesn't comply with the subscriptions.json REST spec.

For example, you may click the Try It button on Subscriptions - List API and use an incorrect API version:

GET https://management.azure.com/subscriptions?api-version=2020-01-02

{
  "error": {
    "code": "InvalidApiVersionParameter",
    "message": "The api-version '2020-01-02' is invalid. The supported versions are '2020-01-01,2019-11-01,2019-10-01,2019-09-01,2019-08-01,2019-07-01,2019-06-01,2019-05-10,2019-05-01,2019-03-01,2018-11-01,2018-09-01,2018-08-01,2018-07-01,2018-06-01,2018-05-01,2018-02-01,2018-01-01,2017-12-01,2017-08-01,2017-06-01,2017-05-10,2017-05-01,2017-03-01,2016-09-01,2016-07-01,2016-06-01,2016-02-01,2015-11-01,2015-01-01,2014-04-01-preview,2014-04-01,2014-01-01,2013-03-01,2014-02-26,2014-04'."
  }
}

In this case, the error message will be revealed by Azure CLI. We will work with ARM team to fix this incorrect behavior.

Error message is improved in #15550.
