publicPath proprety not working in devServer

[stansab]

I want to serve my application on localhost:3001/admin in development environment.
I put the following config :

        build: {
            scopeHoisting: true,
            vueRouterMode: 'history',
            publicPath: "/admin/" 
        },
        devServer: {
            publicPath: "/admin/", 
            port: 3001,
            proxy: {
                // proxy all requests starting with /api
                '/api': {
                    target: 'http://localhost:8080',
                    changeOrigin: true,
                }
            }
        },

application responds on localhost:3001/admin but failed to load app.js because it looks at localhost:3001/app.js instead of localhost:3001/admin/app.js

same problem for me.
It seems that we can’t set a publicPath during development
