I have been trying to track this issue down for weeks now. First I was getting this error from a dashboard app and the "Mobile App Manager" app. I used Device Data app to determine that the device with the attribute "Button" was coming from a child instance of "Virtual Keypad" app. I removed that app. I have recreated all my dashboards from scratch. I have removed, reinstalled, and rebuilt my Virtual Keypad from scratch. I STILL get the ">1024 character" error in my logs.
I have determined that it seems to have something to do with the mobile app. When I open the Hubitat mobile app on MY phone (an Android Pixel 5a), I get two instances of this error message generated by "Mobile App Manager" in my Hubitat log. When I open the Hubitat mobile app on my wife's phone (iPhone 13) there are no errors generated in the Hubitat log. We both have access to the same 2 dashboards on both of these devices.
I have uninstalled and re-installed the Hubitat app on my phone, and it still produces this error in Hubitat when I open the app on my phone.
Does anybody have any idea why this is happening?
note app331 is "Mobile App Manager", which appears to be an internal built-in app that is part of Hubitat itself and there seems to be no other information I can gather about it.
