Error while publishing Potlt from Designer to MWS


I have designd aportlet using Designer. while publishing it to MWS, I am getting an error which is shown in the attached snapshot.

Can anyone please check on the error and let me know the issue due to which the error may be coming.

When connecting to MWS from Designer, what credentials are you using? We highly recommend using user ‘sysadmin’ to avoid permission issues when deploying.
