Not sure if this is the same problem, but I'm getting this error.
I don't get this message when opening a new app, but it does appear very quickly in an opened app during navigating via sheet links in KPI objects. It allows two or three goes then seems to stop working, opening a blank tab but with this error, however the app is still useable using the sheet selector top right. I can't locate any error details in the QS logs.
I'm using 2.2.4 but will be upgrading to a later version and hope this goes away.
