How to exclude node_modules from create-react-app testing?

I want to make tests of my create-react-app using jest.

One of node_modules have test-error,

but I don't want jest to work with node_modules folder.

In the documentation I found configuration property "collectCoverageFrom" and tried to use itin my package.json:

  ....
  "scripts": {
        "start": "react-scripts start",
        "build": "react-scripts build",
        "test": "react-scripts test --env=jsdom ",
        "eject": "react-scripts eject"
  },
  "jest": {
        "collectCoverageFrom": [
            "!/node_modules/*"
         ]
  }

But there is nothing changed.
