Azure "inner exception"

I am setting up Azure Account Settings in OctopusDeploy.
I fill in Subscription ID, Client App ID, Tenant ID and Password.
When I click “Save and Test” I eventually get “Service returned error. Check InnerException for more details”.
The Raw Log shows:
Task ID: ServerTasks-12703
Task status: Failed
Task queued: Friday, December 2, 2016 11:18 AM

Server version: 3.3.14+Branch.master.Sha.94cbad9d1e5d9a9515a90f390455374b9fbe30f8

                | Failed: Test Azure account 

11:20:30 Fatal | Service returned error. Check InnerException for more details

I think the Azure API returns a json payload with the inner exception details ?
Where can I get that?

Hi Tom,

The bad news is you can’t. The inner-exception message is not being logged.

I realize this is not at all helpful. I have created an issue to improve that error logging.

In the meantime, you will likely get a more informative error if you simply try to use that account in your deployment process.

I apologize that this isn’t ideal. If there’s any other way we can assist with getting your Azure Service Principal setup, please let us know. Did you create your Service Principal using the PowerShell script from this page?
