How to get Readable error response from javascript Fetch api?
I finally cracked this. The text is hidden inside promise within response object, so it needs to be handled like a promise to see it.
1 2 3 4 5 6 7 8 9 10 11 12 | fetch(bla) .then(res => { if(!res.ok) { res.text().then(text => throw Error(text)) } else { return res.json(); } }) .catch(err => { console.log('caught it!',err); } |
