We have a number of shortcuts that build a HTML with JS in a Text action. We then base64 encode that Text action and then use the URL action to parse it as "data:text/html;base64, Base64 Encoded". We then open the URL with the Open action.
This works perfect in iOS on iphone and Ipad. Now that macOS supports Shortcuts we tried our automations and all of them fail to open the URL. The error we get is "Shortcuts could not open the app for the URL scheme "data" because the app is not installed on this device
Any ideas would be greatly appreciated
