Description of the error

A minimalistic repo that mimics my current project to reproduce errors in IE11 that seem to be related to namespaced store.

When a module folder in store is included in the dev build, it leads to the current error in IE 11.

These errors expand to followings.

script 1002

script 5007

---

However, when the modules folder is deleted, the error disappears. The weirdest part is that I do not even load the modules folder in store/index.js. I use babel-polyfill and event-source-polyfill in the nuxt.config.js, however that did not solve the issue.

Steps to reproduce

1. Install dependencies and open http://localhost:3000/cs in IE 11
2. npm run dev
3. The errors should pop-up in the console
4. Remove modules folder from store
5. Stop the dev build and run it again. Open a new window in the browser to assure nothing is cached
6. The errors should not appear this time
