Running azure-cost without any arguments results in an exception

[HansDeMulder-VRB]

When running the azure-cost cli without any arguments, an exception is shown. I personally would expect the help information to be shown.

$> azure-cost

[welcome]

Thanks for opening your first issue! Reports like these help improve the project!

The default command is the accumulated cost command. But then it should work correctly of course :-)

Can you try with a --debug added to get the underlying issue?

[HansDeMulder-VRB]

Of course. It seems like it can't find my default subscription id from the Azure CLI (I did do az login beforehand though).

PS C:\> azure-cost --debug
Version: 0.50.0.0
No subscription ID specified. Trying to retrieve the default subscription ID from Azure CLI.

[HansDeMulder-VRB]

Would it be an idea to catch the exception and provide a proper error message, including some tips to resolve the issue on the users' end?

[mivano]

You are right. A good reminder for me to look into this.
