Problem during loading Mac App Store icon

Hi. I’m trying to show the default badge for Dr.Cleaner for OS X but I obtain this error if I try to load app’s icon:

{"code":{"code":"4","name":"Not Found"},"errorMessage":"No Asset found for AssetToken 'Purple7/v4/12/85/0c/12850ccf-7a27-be3f-122c-755c422f60e3/source'","correlationKey":"YJIEQNPJTGYKGECHGS4ITQO6NM"}

If I visit the iTunes Store’s page I can see a different URL of the icon: https://a2.mzstatic.com/us/r30/Purple7/v4/12/85/0c/12850ccf-7a27-be3f-122c-755c422f60e3/icon128-2x.png

Can You solve this problem?
Thanks a lot for your awesome work!
