Nginx How to apply headers to a specific file without breaking the other rules

I have an nginx setup with several folders with aliases

        location /some-path {
            alias ../../path/to/folder1/www;
        }
        location /some-path-2 {
            alias ../../path/to/folder2/www;
        }

Every folder has one specific file that I'd like to be served with a header.

But when I try to add a rule for that file, the other rules stop working. This part I took from several answers here on stackoverflow:

        location ~* .*file.name$ {
            add_header 'Header' 'value';
        }

Then requesting /some-path/file.name and /some-path-2/file.name results in 404

How should I configure nginx to add these header rules and then fall back to the other rules?

There are several variants of how to solve this issue. But each of them related to copy-paste a part of the configuration.

First variant

You may define separate location for each path

location ~ /some-path/file.name {
    alias ../../path/to/folder1/www;
    add_header 'Header' 'value';
}

location ~ /some-path-2/file.name {
    alias ../../path/to/folder2/www;
    add_header 'Header' 'value';
}

It would work because locations with regular expressions would be processed first.

Second variant

You may use nested locations

location /some-path {
    alias ../../path/to/folder1/www;
    location ~ file.name$ {
        add_header 'Header' 'value';
    }
}
location /some-path-2 {
    alias ../../path/to/folder2/www;
    location ~ file.name$ {
        add_header 'Header' 'value';
    }
}

Third variant

map $uri $path_alias {
    default "";
    ~/some-path "../../path/to/folder1/www";
    ~/some-path-2 "../../path/to/folder2/www";
}
server {
    location ~ ^some-path {
        alias  $path_alias;
        location ~ file.name$ {
            add_header 'Header' 'value';
        }
    }
}
