My taskpane is on URL https://presimax.in/testhome And dialog box is on https://presimax.in/word

                        var jsonMessage = JSON.stringify(messageObject);

                    }
                });

        }());  
        }, 10000);
        </script> 
    </body>
</html>

This configuration throws an error OSF.DDA.Error code: 7000 message: "You don't have sufficient permissions for this action."

And also this warning,

"Tracking Prevention blocked access to storage for https://appsforoffice.microsoft.com/lib/1/hosted/office.js."

I don't know the reason, it was working initially for 2 months but now it is giving this error.

Thank you in advance.
