Cannot listen on privileged ports

[m1cm1c]

Description

When trying to listen on a privileged port (< 1024), a "permission denied" error is printed even though the application is run via sudo:

$ sudo npx serve -s build -l 80
file:///path/to/my/project/webapp/node_modules/serve/build/main.js:211
    throw new Error(`Failed to serve: ${error2.stack?.toString() ?? error2.message}`);
    ^
