Proxy does not work in localhost with create-react-app and deno server

Question

I want to access Apis in Deno server from a React app. I added proxy to the package.json file but I got this error:

options.allowedHosts[0] should be a non-empty string.

I found a similar question Invalid options object. Dev Server has been initialized using an options object that does not match the API schema, I followed the answer by installing the http-proxy-middleware in the react project and add the setupProxy under the src folder:

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

module.exports = function(app) {
  app.use(
    '/',
    createProxyMiddleware({
      target: 'http://localhost:5000',
      changeOrigin: true,
    })
  );
};

I followed also what mentioned in the documentation, however I still have the same error:

Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.
 - options.allowedHosts[0] should be a non-empty string.

I'm using react-scripts v5.0.0 and typescript v4.6.2.
