Nginx: псевдоним и try_files с $ args

Когда я пытаюсь использовать try_files с участием ?$args в location /api/v1 Я получаю ошибку 404. Без нее все работает нормально. Любая идея?

Конфигурация Nginx

server {
    listen  80;
    server_name domain.com;

    index index.php;
    root  /home/ec2-user/dev.domain.com.br/webroot/default/web;

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        fastcgi_pass    127.0.0.1:9000;
        fastcgi_index   index.php;
        fastcgi_param   SCRIPT_FILENAME  $request_filename;
        include         fastcgi_params;
    }

    location /api/v1 {
        alias /home/ec2-user/dev.domain.com/webroot/apiv1/web;

        # Works, but don't parse args.
        try_files $uri /api/v1/index.php; ## << WORKING

        # Do not work. Error 404.
        try_files $uri /api/v1/index.php?$args; ## << ERROR

        location ~ \.php$ {
            fastcgi_pass    127.0.0.1:9000;
            fastcgi_index   index.php;
            fastcgi_param   SCRIPT_FILENAME  $request_filename;
            include         fastcgi_params;
        }
    }
}
