Webpack Dev Proxy server does not redirect to my api backend

I'm trying to redirect the routes " link " to " link " where an Apache server runs.

This is my webpack dev server configuration:

devServer: {
    publicPath: '/build/',
    port: 3000,
    proxy: {
        '/api': {
            target: 'http://gestios.loc/api'
        }
    },
    historyApiFallback: true
}

When I try to access link I receive a 404.

Request URL:http://localhost:3000/api/calltek/apps?permalink=empresas
