When attempting to register in production the registration endpoint returns
"error_description": "iss value is not in valid format"
The Nationwide documentation states:
> If you are onboarding with our live service, the value in the outer jwt should match software_id from your SSA. If you are registering your app in the Sandbox, the value in the outer jwt should match TPP_orgid from your SSA
I am using the software_id from the SSA used to attempt registration.
