Getting 500 error when adding payment profile to existing customer profile

[chartierpw]

Is there anything going on with the sandbox?  I am able to retreive the existing customer profile, when I attempt to add a payment profile to it I get a 500 error when I execute the  controller, IE (vb code);

Dim controller = New createCustomerPaymentProfileController(request)

Try

    controller.Execute()

Catch ex As Exception
    pErrorMsg = ex.Message ' "The remote server returned an error: (500) Internal Server Error."
End Try

I am connecting using TLS v1.2, so that shouldn't be an issue.

Any suggestions
