I am using bootstrap 4 in my angular application, the dropdown function is working perfectly in mode developer but in production mode, I got this error:

Uncaught Error: DROPDOWN: Option "popperConfig" provided type "window" but expected type "(null|object)".

The problem is with bootstrap 4.4+ version, change to bootstrap 4.3.1 and will works fine.

You can install it from npm and then add the path into angular.json file (styles and scripts configs):

npm install [email protected]

or use urls in your index.html

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>

We have the same issue at the moment, but only with IE11.

Update 1: As of right now I can tell you, that it hast something to do with the angular / typescript version. I reverted our app from 8.2.14 / 3.5.3 back to 8.0.0 / 3.4.3 and it starts working again. Now we will go up the different version to find out, what version change cases the problem.

Update 2: After testing multiple combinations of angular versions, we found out that these two packages caused our problem:

"@angular-devkit/build-angular"

"@angular/cli"

A newly created angular 8 project uses the follwing versions:

"@angular-devkit/build-angular": "~0.803.20"

"@angular/cli": "~8.3.20"

But with 8.3.x it´s not working! Reverting these two packages to the latest 8.2.x version fixes our problem!

"@angular-devkit/build-angular": "0.802.2"

"@angular/cli": "8.2.2"
