  *** Variables ***
  ${headers}        {'content-type': 'application/json', 'authorizationFlag':'N'}
  
  *** Test Cases ***
  Read API
      Create Session    CLM    http://172.20.33.224:8080/clm-reg/rest/dataservice/1/CLM/1
      ${resp}    Get Request    CLM    /RegistrationRequestDetails/json/583d8b14498e021b2f93a773    headers = ${headers} 
      Log to console    ${resp}
  </code></pre>
  
  <p>I am getting the error : </p>
  
  <pre><code>AttributeError: 'unicode' object has no attribute 'items'
