Trying to enable WS-Security in Rule-Service-SOAP and testing via SOAPUI, not sure what is the issue here

https://community.pega.com/knowledgebase/articles/data-management-and-integration/86/enabling-web-service-security-service-soap-rule 

Passing the below header via SOAP UI in the soap envelope

   <soapenv:Header>
      <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
         <wsse:UsernameToken wsu:Id="UsernameToken-676D7DF24681512F9E16316474247873">
            <wsse:Username>user</wsse:Username>
            <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">password</wsse:Password>
         </wsse:UsernameToken>
      </wsse:Security>
   </soapenv:Header>

error message i am seeing

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:soapenc="http://www.w3.org/2003/05/soap-encoding" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
