// remember to RETURN res.json() like this:
    .then(res => {
      	return res.json()
   	})

// alternatively you can use:
	.then(response => response.json())

// this is my CODE EXAMPLE:
   fetch("/myUrl", {
      method: "GET",
    })
      .then((res) => {
        return res.json(); 		// <-- see?
      })
      .then((data) => {
        console.log(data);
      });

// if your code is still not working try: 
 fetch("/myUrl", {
      method: "GET",
    })
      .then((data) => {
        console.log(data);
      });
// and in your console you should see object "Response". 
// Unfold and check "status" property. 
// If it's 500 you've probably made a misspelling in your server config file.
// If it's 200 you're close to find solution! I wish you luck!
