'ExtraClass' of type string is incompatible with the type array expected by parameter $args of SilverStripe\View\ViewableData::create().

It seems like SilverStripe\Forms\TextField::create('Title', '') can also be of type object; however, parameter $args of SilverStripe\View\ViewableData::create() does only seem to accept array, maybe add an additional type check?
