nginx不能实现正则批配，是什么原因？

Question

我的nginx -V信息如下：

nginx -V
nginx version: nginx/1.14.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC) 
configure arguments: --prefix=/usr/local/nginx --add-module=/usr/local/src/lua-nginx-module-0.10.13 --add-module=/usr/local/src/ngx_devel_kit-0.3.0

我的nginx vhost配置文件如下：

server{
    listen       80;
        server_name  t1.xxx.com;
        
      location / {
            root /t1/html;
            index index.html index.htm;
      }
  
    location /test_lua { 
      default_type 'text/plain'; 
      content_by_lua 'ngx.say("hello, lua")'; 
    }
     #这个就是无法批配并正常显示以下相应图片链接信息，求解！！！
    location ~* ^((\/manager)(\/\w+)(.+\.(jpg|jpeg|gif|png))_(\d+)+x(\d+)+\.(jpg|jpeg|gif|png))$ {
            set $para1 $1;
            set $para2 $2;
            set $para3 $3;
            set $para4 $4;
            set $para5 $5;
            set $para6 $6;
            set $para7 $7;
            set $para8 $8;
            set $para9 $9;
            default_type 'text/plain';
            content_by_lua_block {
                    ngx.say(ngx.var.para1)
                    ngx.say(ngx.var.para2)
                    ngx.say(ngx.var.para3)
                    ngx.say(ngx.var.para4)
                    ngx.say(ngx.var.para5)
                    ngx.say(ngx.var.para6)
                    ngx.say(ngx.var.para7)
                    ngx.say(ngx.var.para8)
                    ngx.say(ngx.var.para9)
            }

    }

  
    error_log   /usr/local/nginx/logs/error_t1.log    error;
      access_log  off;
}

求大师解答！！！感谢！！！
