there is a reference to the asset iowa-bar.js
in the code, there are places where the ".style" property of elements are checked, but, if the object (menudrawermobile) doesn't exist, it will throw an error.
Please consider updating.
Proposed Solution
Move iowa-bar.js to uids_base and remove it from 3.x?
