Hi there, I am trying to login to [backendless.com](http://backendless.com) via REST api. Below is my code. On Fuse debug console I didn’t see anything, not even errors. Whenever I test via POSTMAN it response back. Anything wrong with parsing header or body?

```auto
    function login_clicked()
    {
        fetch('http://api.backendless.com/v1/users/login&#39;,
        {
            method: 'POST',
            headers: {
                    "application-id": authKeys.appID,
                    "secret-key": authKeys.appSecrete,
                    "Content-type": "application/json",
                    "application-type": "REST"
                    },
            body: JSON.stringify({
                "name":"admin",
                "password":"admin123"
            })
        })
        .then(function(result){
            if(result.status !== 200){
                console.log("Something went wrong" + result);
                return ;
            }
            return result.json();
        })
        .then(function(responseObject){
            console.log("------------");
            console.log(JSON.stringify(responseObject));
            console.log("**");
        });
    }

```

Hi!

If the fetch fails are you catching the error? Try to add a `.catch(function(err) { console.log(err); })` to see if and why it fails
