I am getting this error message when opening a page. At first, I thought it is caused by a widget on my page. Unfortunately, it is still showing up after removing everything from my page (except an empty dataview). The page is the homepage and is also accessible via the navigation. When navigating to it via the navigation, it works. When doing the same via the home page microflow (I need to use a microflow because of deeplinks) I am getting this error. Could it be related to the deeplink module/deeplink home microflow? Any Ideas? Update: I removed the Deeplink home microflow and tried to call the same microflow for the home page and for the navigation item. I still get the same error. When loging in or refreshing the page, it throws this error. When using the navigation, everything works fine.
Maybe you could also check if there is a page which is called twice during the process.
Do you checked the permissions? Maybe there is an issue on the access rules for an attribute.
