Custom nav walker not loading

[dragosite]

Hi there,

Custom nav walker doesn't seem to be loading from header.blade.php

@if (has_nav_menu('primary_menu'))
	{!! wp_nav_menu([
		'theme_location' => 'primary_menu',
		'container'		 => false,
		'menu_class'	 => 'primary-menu',
		'walker'		 => new Primary_Menu_Nav_Walker()
	]) !!}
@endif

Edit: dumping wp_nav_menu returns False.

Thanks
