reactjs - What is wrong with config.yml file?

Question

I'm learning how to work with react and circleci.

Here is my testing config.yml file which is a demo from circieci

orbs:
  node: circleci/[email protected]

version: 2.1

workflows:
  app-tests:
    jobs:
      - node/test

When I commit my code to github and circleci will have an build error as showing below:

Invalid orb reference: 'circleci/node4.0.0'. 

What have I missed?

Please give me some hints which could probably save me couple of hours. I'm new to CircleCI. : (
