Handle a 500 response with the fetch api
Working Solution
Combining then with catch works.
fetch('http://some-site.com/api/some.json') .then(function(response) { // first then() if(response.ok) { return response.text(); } throw new Error('Something went wrong.'); }) .then(function(text) { // second then() console.log('Request successful', text); }) .catch(function(error) { // catch console.log('Request failed', error); });Details
fetch() returns a Promise containing a Response object. The Promise can become either fulfilled or rejected. Fulfillment runs the first then(), returns its promise, and runs the second then(). Rejection throws on the first then() and jumps to the catch().
