Switching security mode to Prototype/demo fails to show up page in Responsive Browser

Hi, I am on Mendix Studio Pro 8.1. I am able to see the page properly in Responsive Browser when I have my Security set to “Off”. When I switch to “Prototype/Demo”, Run Locally and tried to view in responsive browser, it doesn’t show the page et al and displays like below:  I also see the following error in Studio Pro Console.   Any inputs what could be possibly going wrong, is highly appreciated. Update: I found the following documentation to resolve this. However, even implementing this did n’t help: Any takers please? Regards Mohan

Did you set the correct microflow in the after startup? You reffer to *.microflow which is not correct?
