FETCH IE11：第二次提取在 ie 11 中不起作用

Question

the first time fetch is called, everything works correctly. on the second call, I get false. It works correctly in Chrome. Polyfill fetch is connected.

The code below translates to ES5 before uploading it to the server. I have hidden some variables.

 const url = `Fake url for example`; function addData(data) { console.log("Affiche", data); const randomAffiche = data.data[getRandomInt(data.data)]; const date = randomAffiche.PROPERTY_DATES_VALUE.split('-')[1]; eventImgElem.src = randomAffiche.IMG; eventTitleElem.innerHTML = randomAffiche.NAME; eventTitleElem.href = randomAffiche.DETAIL_PAGE_URL; eventLink.href = randomAffiche.DETAIL_PAGE_URL; eventDate.innerHTML = getMonth(date); eventLink.innerHTML = randomAffiche.PROPERTY_VENUE_VALUE; whereToGoLink.href = '/kudago/'; } function fetchData(city) { try { fetch(url + city) // This fetch is returned data = false. Why? .then(data => { data.json() .then(data => { console.log("fetchData", data); addData(data); }) }) } catch (e) { console.log(e); } } function getCity() { const url = "fake url for example"; try { fetch(url) // This fetch is good .then(data => { data.json() .then(data => { console.log("getCity", data) if (data.data) { fetchData(data.data.name); } else { console.log("Error getCity", data); } }) }) } catch (e) { console.log(e); } } getCity();

This method helped me https://developer.mozilla.org/ru/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent

encodeURIComponent(url)

IE 11 did not understand the cyrillic alphabet. this will help those who have Cyrillic in the request.
