SharePoint Online CustomAction redirect error
I am working on an add-in for SharePoint Online. I have a problem with the redirect in the <CustomAction> element where the button subscribes to <CommandUIHandler Command = "Redirect.Command" CommandAction = "http://www.bing.com" /> On the redirect page I get an error like in the screenshot There is no additional information and I have no idea what is wrong. Maybe some of you have encountered such a problem?
