Angular 6 Uncaught TypeError: Cannot assign to read only property 'exports' of object '[object Object]' ;

[fmvgs]

Hello,

I have an angular (version 6) appplication and I'm trying do use twilio-video.
When I do ng serve it works ok.
But when I do a ng build --prod, deploy and try to access I get the errors on the browser.

I've tested with a mininal angular app from version 6 to 11.
For versions 6 and 7 I get the same error but for versions 8 to 11 the application loads in the browser.

• I have verified that the issue occurs with the latest twilio-video.js release and is not marked as a known issue in the CHANGELOG.md.
• I reviewed the Common Issues and open GitHub issues and verified that this report represents a potentially new issue.
• I verified that the Quickstart application works in my environment.
• I am not sharing any Personally Identifiable Information (PII)
  or sensitive account information (API keys, credentials, etc.) when reporting this issue.

Code to reproduce the issue:

Initialize an simple application (commands just for 6 and 7 that would not work and for version 8 the lowest version I tried that worked)

npx -p @angular/cli@6.2.9 ng new sample-application
npx -p @angular/cli@7.3.10 ng new sample-application
npx -p @angular/cli@8.3.29 ng new sample-application

on tsconfig.json add

"skipLibCheck": true

on app.component.ts add import

import { createLocalTracks } from 'twilio-video';

and add ngOnInit method

  ngOnInit(): void {
    createLocalTracks({
      audio: true,
      video: { width: 640 }
    });
  }

Expected behavior:

The app would load in browser with no error

Actual behavior:

On Chrome the error message says:
