API fetch is not responding

I was working on a React APP which fetches data from https://restcountries.com/v2/all and now I have an error.

useEffect(() => {
  fetch(`https://restcountries.com/v2/all`)
    .then((r) => r.json())
    .then((data) => {
      if (data !== undefined) {
        setCountries(data);
      } else {
        alert('Can´t Load Data');
      }
    });
}, []);

**

use this format with header

** ##

// Example POST method implementation:
async function postData(url = '', data = {}) {
  // Default options are marked with *
  const response = await fetch(url, {`enter code here`
    method: 'POST', // *GET, POST, PUT, DELETE, etc.
    mode: 'cors', // no-cors, *cors, same-origin
    cache: 'no-cache', // *default, no-cache, reload, force-cache, only-if-cached
    credentials: 'same-origin', // include, *same-origin, omit
    headers: {
      'Content-Type': 'application/json'
      // 'Content-Type': 'application/x-www-form-urlencoded',
    },
    redirect: 'follow', // manual, *follow, error
    referrerPolicy: 'no-referrer', // no-referrer, *no-referrer-when-downgrade, origin, origin-when-cross-origin, same-origin, strict-origin, strict-origin-when-cross-origin, unsafe-url
    body: JSON.stringify(data) // body data type must match "Content-Type" header
  });
  return response.json(); // parses JSON response into native JavaScript objects
}
}, []);

You are getting a CORS error which means target domain of api (restcountries) does not allow other domains to fetch data. The solution to this problem is a server side browser or headless browser. Like selenium and puppeteer

https://github.com/puppeteer

But i have tested and api is giving me data in browser with same fetch code. I cant reproduce the problem. Its an issue with something else
