Describe the issue

Hi everyone,

I included this library in my project:

yarn add @popperjs/core @eonasdan/tempus-dominus

Then required it:

import { TempusDominus } from '@eonasdan/tempus-dominus';

But I get this error when running the yarn watch command

 ERROR  Failed to compile with 1 errors                                                                                                     3:03:53 PM

 error  in ./node_modules/@eonasdan/tempus-dominus/dist/js/tempus-dominus.esm.js

This is likely an issue with the null check (?). I don't know enough about webpack to help you beyond that.
