javascript - fetch resolves even if 404? - Stack OverflowA fetch() call is only rejected if the network request itself fails for some reason (host not found, no connection, server not responding, etc...). Any result back from the server (404, 500, etc...) is considered a successful request from the promise point of view.
I'm playing around with fetch, and I noticed that only Chrome displays an error when a resource I am fetching doesn't exist (aka a 404): Both Edge and Firefox don't do that, and 404 errors using fetch don't seem to trigger a NetworkError to have my catch error handler to get notified.
I'm trying to handle a 404 in Chrome with this fetch () function. function promiseBatchDomains(domainsToQuery) { var batchSize = domainsToQuery.length. var currentDomain = 0. var promises = domainsToQuery.map(domain => ( fetch(`https://api-url-omitted/${domain}`) .then( res => { if (res.ok) { return res. } else { throw Error(res.statusText)

Using the Fetch API - Web APIs | MDN - MDN Web DocsThe fetch () function returns a Promise which is fulfilled with a Response object representing the server's response. You can then check the request status and extract the body of the response in various formats, including text and JSON, by calling the appropriate method on the response.

When That's Not So Fetch: Error Handling With fetch()According to the fetch() MDN, the Promise object returned by the fetch() call is rejected (throws an error) only when "a network error is encountered." This means that fetch() Promises do resolve despite encountering client-side HTTP errors such as 404 and do not throw errors during the fetch.
