setupProxy file in CRA makes react-scripts start fail with Command failed with exit code 1 error

Question

I've added the following setupProxy file according to the example in the docs:

const proxy = require('http-proxy-middleware');

module.exports = function (app) {
    app.use(
        '/address',
        proxy({
            target: 'https://zip-cloud.appspot.com/api',
            changeOrigin: true,
        })
    );
};

But whenever I want to start the npm start command it fails with the following error: error Command failed with exit code 1.

I have no clue why it's not working. I'm using the newest CRA version and I'm using typescript. Any help would be appriciated!

Try:

const { createProxyMiddleware } = require('http-proxy-middleware');

module.exports = function (app) {
    app.use(
        '/address',
        createProxyMiddleware({
            target: 'https://zip-cloud.appspot.com/api',
            changeOrigin: true,
        })
    );
};
