Empty $proxy_extensions

I created a nginx template for my Yii2 application, but the generated config for the domain gives me an empty $proxy_extensions

TEMPLATE:

		location ~* ^.+\.(%proxy_extensions%)$ {
			expires max;
			fastcgi_hide_header "Set-Cookie";
		}

GENERATED CONFIG:

		location ~* ^.+\.()$ {
			expires max;
			fastcgi_hide_header "Set-Cookie";
		}

Have anyone have some tips to fix it? Or knows why this happens?

FULL TEMPLATE:
root@hestiacp:/etc/nginx/conf.d/domains# cat /usr/local/hestia/data/templates/web/nginx/php-fpm/yii2.tpl
