처리되지 않은 약속 거부 구문 오류 Internet Explorer
Vuejs, vuex, webpack, babel-polyfill, axios를 사용하고 있습니다.
이 오류는 프로덕션 서버의 Internet Explorer에서만 나타납니다.다른 모든 브라우저 및 로컬호스트에서 동작합니다.왜 이런 일이 일어나는지 모르겠다.
vuex 및 axios 포럼에서 이 문제를 찾아보려고 했지만 운이 없었습니다.
도와주셔서 감사합니다.
다음은 IE11 콘솔에서 보내는 메시지입니다.
감사해요!

이 오류는 작성한 약속이 거부되어 명시적이지 않은 경우 표시됩니다..catch할 수 있을 것 같아요.내가 제안할 수 있는 유일한 것은 당신의 모든 코드를 확인하고 모든 약속들이.catch'어느 시점에는'
또한 이 약속이 거부된 이유와 코드에서 정확히 어디서 발생했는지 알아내는 데 도움이 되는 이벤트 청취자가 있습니다.
window.addEventListener("unhandledrejection", function (event) {
console.warn("WARNING: Unhandled promise rejection. Reason: " + event.reason, event);
});
