IE11 - SecurityError zone.js (192,25)

[kevinkuszyk]

I'm seeing the following error intermittently both before and after applying the fix for the Can't execute code from a freed script error (#933).

Here is an example of before:

And after:

This is a drill down into the sources:

I've pushed a sample repro at kevinkuszyk/angular-ie-freed-script-error. IE may not display the error the first time the app is loaded, but refreshing a few times is usually enough to trigger it.

@kevinkuszyk , thank you for the sample, I will try to reproduce it.

[JiaLiPassion]

@kevinkuszyk , I think I may find the possible reason, when run ng serve, there will be websocket to connect angular web app with angular dev server, and every time refresh IE page, there will be a new web socket was created.

and in IE, the maximum websocket connections are 6 by default, https://msdn.microsoft.com/ja-jp/library/ee330736%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396.
so error occurs, you can change the number by modify the registry.

\HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_WEBSOCKET_MAXCONNECTIONSPERSERVER

and add a key, iexplore.exe（REG_DWORD) modify the value to 2~128.

I just modify to 50, and the error gone.

Thanks @JiaLiPassion, that seems to have fixed the security error.

\HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\

Doesn't seem to exist for me (on Windows 10 build 1709).

[JiaLiPassion]

@todthomson , you can search HKEY_LOCAL_MACHINE , if not exists either, you need to created those keys yourself.

@todthomson
The registry key can be found here:
HKEY_CURRENT_USER (or HKEY_CURRENT_USER)\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_WEBSOCKET_MAXCONNECTIONSPERSERVER

same here...

I'm still seeing the "Security Error" even after applying @JiaLiPassion fix. I've also addressed the error in #933 and followed the directions in the Angular and Internet Explorer article. Any subsequent navigation leads to a blank page and no console errors. I've restarted the browser and even restarted my VM and confirmed the registry change is present. Is there any other workaround?

[uberspeck]

FWIW, I added the following to my polyfills.ts and it seemed to fix the issue

import 'core-js/es7/object';
import 'core-js/es7/array';

[JiaLiPassion]

@uberspeck, yeah, you have to import those polyfills to make es6 APIs work property in IE.

thank you @JiaLiPassion for the registry fix! its working for me. (But i dont know how u figure out this fix. 👍 )

[chowdam]

issue resolved after adding below in polyfills.ts file:
import 'core-js/es7/object';
import 'core-js/es7/array';

[JiaLiPassion]

will close for now.
