getcontext()method is not working as per documentation in jira connect app

[Ashok Chelimilla {Appfire}]

I used below code to get issue key and project id but it's returning undefined. Please help on this  ?

AP.context.getContext(function(response){
  console.log("Jira Issue Key", response.issue_key);
  console.log("Confluence page id", response.pageId);
  
});
