How to listen for more than one Proxy event? (proxyReq and error)

[TimGuendel]

Hello,
This might be a stupid question, but how do I extend my proxy config to listen to 'proxyReq' and 'error' at the same time?

    proxy: {
        proxies: {
            '/api': {
                target: process.env.BACKEND_URL,
                changeOrigin: true,
                rewrite: path => path.replace(/^\/api/, ''),
                configure: (proxy, _options) => {
                    proxy.on('proxyReq', (req, _res, _proxyRes) => {
                        console.log('proxyReq');
                    });
                   
                   // Here I need this too:
                   // proxy.on('error', (err, req, res) => {
                   //     console.log('err');
                   // });

                },
            },
        },
    },
