Directives are doing a fatal error

I'm getting the following:

[18-May-2018 14:07:52 UTC] PHP Fatal error:  Uncaught TypeError: Argument 2 passed to Illuminate\View\Compilers\BladeCompiler::directive() must be callable, array given, called in /srv/www/mywebsite.com/current/vendor/webstractions/sage-xpress/src/Blade/DirectivesRepository.php on line 20 and defined in /srv/www/mywebsite.com/current/web/app/themes/sage/vendor/illuminate/view/Compilers/BladeCompiler.php:474
