Updating scale with no scaling profile produces different error based on how you update it.

[mimckitt]

Describe the bug

Customers can create a scale set with no scaling profile. This can easily be done via the Azure portal.

If a customer attempts to change the upgrade policy mode of the scale set using the following:

az vmss update --name myScaleSet --resource-group myResourceGroup --set upgradePolicy.mode=Automatic

They get the following error (which is expected):

(BadRequest) Virtual Machine Scale Set with 'Automatic' Upgrade Mode must contain a VM Profile Code: BadRequest Message: Virtual Machine Scale Set with 'Automatic' Upgrade Mode must contain a VM Profile

If they try to change the upgrade policy using the following:

az vmss update --name myScaleSet1 --resource-group myResourceGroup --upgrade-policy-mode Automatic

The get the following error:

The command failed with an unexpected error. Here is the traceback: 'NoneType' object has no attribute 'mode' Traceback (most recent call last): File "/usr/lib64/az/lib/python3.9/site-packages/knack/cli.py", line 233, in invoke cmd_result = self.invocation.execute(args) File "/usr/lib64/az/lib/python3.9/site-packages/azure/cli/core/commands/__init__.py", line 666, in execute raise ex File "/usr/lib64/az/lib/python3.9/site-packages/azure/cli/core/commands/__init__.py", line 734, in _run_jobs_serially results.append(self._run_job(expanded_arg, cmd_copy)) File "/usr/lib64/az/lib/python3.9/site-packages/azure/cli/core/commands/__init__.py", line 703, in _run_job result = cmd_copy(params) File "/usr/lib64/az/lib/python3.9/site-packages/azure/cli/core/commands/__init__.py", line 336, in __call__ return self.handler(*args, **kwargs) File "/usr/lib64/az/lib/python3.9/site-packages/azure/cli/core/commands/command_operation.py", line 239, in handler result = cached_put(self.cmd, setter, **setterargs) File "/usr/lib64/az/lib/python3.9/site-packages/azure/cli/core/commands/__init__.py", line 455, in cached_put return _put_operation() File "/usr/lib64/az/lib/python3.9/site-packages/azure/cli/core/commands/__init__.py", line 449, in _put_operation result = operation(**kwargs) File "/usr/lib64/az/lib/python3.9/site-packages/azure/cli/command_modules/vm/custom.py", line 4214, in update_vmss vmss.upgrade_policy.mode = upgrade_policy_mode AttributeError: 'NoneType' object has no attribute 'mode'

Regardless of if the customer attempts to update the upgrade policy mode using --set upgradepolicy.mode=Automatic or --upgrade-policy-mode Automatic the error should be consistent.

(BadRequest) Virtual Machine Scale Set with 'Automatic' Upgrade Mode must contain a VM Profile Code: BadRequest Message: Virtual Machine Scale Set with 'Automatic' Upgrade Mode must contain a VM Profile

NOTE: when using --set upgradepolicy.mode= can be set to Automatic, Manual or Rolling. Same is true for --upgrade-policy-mode. Regardless of if they try to update it to Automatic, Manual or Rolling, the error should be consistent.

Hi @mimckitt,

2.68.0 is not the latest Azure CLI(2.69.0).

If you haven't already attempted to do so, please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.
