Fetch Request Completes Successfully, but Response Object Empty

I have a fetch request within the componentDidMount() method of a React component:

const request = new Request(url, {
    mode: 'no-cors',
    method: 'get',
    headers: {
        Accept: 'application/json'
    }
});

fetch(request)
    .then(function(response) {  
        console.log('Response: ', response);

        return response.text();  
    })
    .then(function(data) {
        // _this.setState({ data: data });

        console.log('Success: ', data);
        console.log('Request succeeded with JSON response', data);
    }).catch(function(error) {
        console.log('Request failed', error);
    });

When the Component loads, I can see the Request being made in the Console and the proper data being returned; however, my Response object is always empty:

Response { type: "opaque", url: "", redirected: false, status: 0, ok: false, statusText: "", headers: Headers, bodyUsed: false }

response.text() returns null, and I'm really uncertain what is going on. I've used the same method before and not had this problem, so I'm uncertain if it's different because of the third-party data source or what.

Any ideas?

I suggest you to follow the comments below the question:

If the reason you’re using mode: 'no-cors' is because the server doesn’t send the Access-Control-Allow-Origin response header in its responses, then mode: 'no-cors' is not the way to fix that. The only way to fix it properly is to either configure the server to send Access-Control-Allow-Origin response header or else change your frontend JavaScript code to make you request through a proxy instead. follow this link...
