In the recent version upgrade of 7.9 in confluence on-premise solution we are not able to consume the HTML content data of an attachment from a wiki page through simple GET request or by calling wiki REST API end point. The first time we are getting only the tag content as "Loading" and I believe that we need to call a separate end point for fetching the content of the attachment that has been added through Wiki macro.
Can you please suggest a guide which I can follow how to construct the second API end point for fetching the content of different attachments of office software (added through macro)?
