未捕获（承诺）：错误：在 IE11 中拒绝访问

Question

Am using Angular 7 in my project and I found this error last day. It is happening only in the deployed site. Not in my local. Also the same issue is not throwing in any other browsers, but in IE11 (Haven't tried any lower versions of IE). This issue was not there before and its been happening from last day only. I tried to figure out the issue. Tried changing polyfills and so on. But nothing worked. Tried this link also. But that is also not resolved. Any help will be appreciated. Thanks in advance

Answer 1

The reason your Promises are causing errors in IE is that Promises are not supported in IE11.

Although, there are ways to add support for them:

• 3rd Party Promise libraries (ie: Bluebird )
• If you are using ES6 syntax, perhaps use a transpiler (ie: Babel )
