HTTPs not supported by webservicequery?

Question

I am trying to consume an https/2 Way SSL service using webservicequery function. I keep getting below error: 
 
 Expression evaluation error at function 'webservicequery': Error evaluating function 'webservicequery' : Cannot convert XML to an internal value of type Number (Integer) (id=1). XML: {[Element: <NS2:Status [Namespace: http://xyz.com/SamlAttributesAppian/namespace/]/>]} 
 
 Wanted to confirm first that https service could be consumed using webservicequery. Thanks!

Some web services require transport-level client certificate authentication when setting up an SSL connection. The Client Certificates page allows you to expose certificates for use by the Call Web Service smart service and the webservicequery() and webservicewrite() expression functions and the HTTP Query smart service and the a!httpQuery() and a!httpWrite() expression functions. 
 
You upload client certificates in admin console. The certificate must be formatted as a PEM file. If the certificate is protected by a password you should enter the password in the password field. This password will not be stored. The certificate will be stored in an encrypted format in the Appian data source.
