Unable to run project locally

Hello,

When trying to run project locally (git clone, npm install, npm run start), everything is compiled successfully, but when I go to localhost:8080, there remains only "Loading..." text and in browser console is following error:
```
TypeError: ctorParameters.map is not a function
http://localhost:8080/vendor.js line 1807 > eval
Line 61
```
Any help appreciated.
