Failed to read property of 'root'.

[Gungo]

My UML design looks like this: https://drive.google.com/file/d/1zcmP_ZzBVvfhH8AZmkZ6FuorrunNFr2A/view?usp=sharing

and running the command in my vue apps directory:

events.js:167
      throw er; // Unhandled 'error' event
      ^
TypeError: Cannot read property 'root' of undefined
