drawerToggleAttribute is not initialized in Polymer 2+. The default value of the property is not available and Polymer requires property to be declared in the properties collection of the component, so that it's value can be set as an attribute.
Expected outcome
The drawer can be opened by tapping on the element with the attribute name same as drawerToggleAttribute's value
