Fetch API, Chrome, and 404 Errors [duplicate]

Answer 1

You can try to handle the error yourself and actually trigger a Promise.reject(). Something like this

fetch("https://httpstat.us/500", {
    method: "head",
    mode: "no-cors"
})
.then(status)
.then(res => res.json())
.catch(function(error) {
    console.log("Error", error);
});

function status(response) {   
    if (response.ok) {
        return response;
    }
    return response.json().then(res => Promise.reject(res));
}
