Angular 2+: Internet Explorer: Unable to get property 'call' of undefined or null reference

Question

In Angular 4.2.4 (Angular-CLI 1.1.3), IE11 I get SCRIPT1002: Syntax error and SCRIPT5007: Unable to get property 'call' of undefined or null reference. I have my polyfills in and I would have assumed that Webpack and Angular-CLI would have done the rest. What am I missing here?

Unable to get property 'call' of undefined or null reference says after it: bootstrap 50034e0a1f93dabcb117 (54, 1) with no indication of a real filename. And Syntax error says it's in vendor.bundle.js (63117,26), which looks like:

window.setTimeout(() => {
    window.removeEventListener('click', suppressClick, true);
}, 0);

Update: Should have been more obvious to me before, but this looks like ES6 code, and it should be compiling down to ES5.

You are getting a syntax error and undefined variables but are not sharing any code. — Raven, Jun 13 '17 at 20:53
Hi BBaysinger , I was getting same error try to delete the package.lock.json and npm install againg , worked for me — Americo Arvani, Jun 20 '17 at 15:16
Are you starting your app with "ng serve" ? Are you using any JQuery code? — Gambo, Jun 23 '17 at 12:18
This could be one of a hundred problems. You might want to share a git repo since this is such a broad problem. As @AmericoArvani mentioned, it's likely to do with your npm installation or packages. — Z. Bagley, Jun 23 '17 at 14:50
Try removing bundling from your webpack config and add source maps to see which file is breaking. It is hard to say without code — Carbosound1, Jun 27 '17 at 13:54
Would You mind checking the solution beneath if it answers Your question? — Hash, Jul 03 '17 at 11:03
@Mark, it didn't fix it for me. I mentioned in my question that I had polyfills in already. — BBaysinger, Apr 18 '18 at 19:30

There could be a lot of problems here as mentioned in the comments but I recently had a problem with browser compatibility and the solution was to use polyfills. Uncomment the following lines:

/** IE9, IE10 and IE11 requires all of the following polyfills. **/
import 'core-js/es6/symbol';
import 'core-js/es6/object';
import 'core-js/es6/function';
import 'core-js/es6/parse-int';
import 'core-js/es6/parse-float';
import 'core-js/es6/number';
import 'core-js/es6/math';
import 'core-js/es6/string';
import 'core-js/es6/date';
import 'core-js/es6/array';
import 'core-js/es6/regexp';
import 'core-js/es6/map';
import 'core-js/es6/weak-map';
import 'core-js/es6/set';

And run your application. It should be working down to IE10 at least it worked out for us. Based on the error message it is likely to work for You as well.

If this doesn't work for you, try this: https://stackoverflow.com/a/50070943/1253298 — BBaysinger, May 29 '18 at 16:17

Try to load jQuery polyfills from assets:

in index.html's head:

  <script src="assets/...">

My take is to try at least https://plugins.jquery.com/webshims/

For anyone still running into this issue, try this:

Angular 2+: IE 11 Unable to get property 'call' of undefined or null reference

If the error you're getting occurs on a hunk of code that looks like this:

window.setTimeout(() => {
    window.removeEventListener('click', suppressClick, true);
}, 0);

...then please let me know if the solution worked or not. I will update this answer, and possibly mark this question as duplicate.

I DO NOT BELIEVE THESE TO BE THE SAME ISSUE AT THIS TIME, AS THE ERRORS OCCURRED ON DIFFERENT CODE IN bundle.js. Someone voted this answer down, without giving any feedback on whether or not these questions have the same solution.

I do not have a way to test this currently, but wanted to direct folks to a possible solution.
