Fetching a string by parsing URL

[sudharshanr]

For some reason, I'm getting it as null. This is my config file:

map $uri $last_path {
~*/(?<pathname>[^/]+)/?$ $pathname;
}

server {
    listen       80;
    root /basefolder;

    error_page 500 501 502 503 504 =
/error5x.html?name=$arg_name&path=$last_path;
   
    location  ~*/error5x.html? {
       alias <static file location>/error5x.html;
     }

    location ~*/path1/  {

        if (-f $document_root/error503.html) {
          return 503;
        }
    ....
}

However, if I update the location directive as below:

location  ~*/error5x.html? {
       alias <static file
location>/error5x.html?name=$arg_name&path=$last_path;
}

I get a file not found error. But when I check the nginx log, I can see that
it is fetching the $last_path variable. Just that it takes it as part of the
file name and throws a 404 error.

Thanks.
