Yes, I have. It could be the reason of this error. I pass the value of SessionToken to the service header in the "before mapping" event. For most of the time this value is empty because I use it only when the user logs into database and gets a valid session token to use some special features in the app.
So basically it looks like for some reason in the version 1.2 of Apper libraries passing empty value to service headers does not generate error but in version 2.1 it throws critical error (in fact it is not an empty value but there is virtually no "SessionToken" present in local storage, because it only appears after succesfull login).
So my first question is what can I do about it?
The second thing is that even when I provide a valid session token, the service named "restservice_GroupList_query" loads incorrect items into my LIST control. Please take look at the screen attached:
The items are unproportionally big and the list does not respond to any clicks (no errors at the console).
And when I swith back to the 1.2 version of library I get valid and clickable list:
So my second question is how do I fix it?
