JiraBodyResponseRelatedIssue

Hey All
I am trying to get the comments which contain attachments using this api:-
API:-> /rest/api/2/issue/‘+jiraIssueId+’/comment/‘+commentId+’?expand=renderedBody

and the api gives me this response:-
Ex:- Screenshot by Lightshot
But for now this api returns the following response body which does not contain any renderedbody
Ex:- Screenshot by Lightshot

Can anyone tell me why this is happening? Are there any changes in the API or response body?
