Typescript version isssue

As per docs ran the ... create-react-app --typescript command. I eject it. yarn start it. The project runs but before server is up after hitting the command yarn startThere is a warning that says "TYPESCRIPT supported versions are >3.2.0 and ❤️.5.0 ".

I’m afraid I didn’t manually upgrade typescript version but did have to run yarn install after ejecting.

The current version of typescript installed is 3.5.1.

Should I consider this warning as serious and degrade my typescript?

EXACT ERROR:

WARNING: You are currently running a version of TypeScript which is not officially supported by typescript-estree.

You may find that it works just fine, or you may not.

SUPPORTED TYPESCRIPT VERSIONS: >=3.2.1 <3.5.0

YOUR TYPESCRIPT VERSION: 3.5.1

Please only submit bug reports when using the officially supported version.

Found related issue in TypeScript ESLint: https://github.com/typescript-eslint/typescript-eslint/issues/577

I think it will be fixed soon.

Per the typescript-eslint docs, I tried to suppress this error by falsifying the warnOnUnsupportedTypeScriptVersion parser option in eslintConfig in package.json:

  "eslintConfig": {
    "extends": "react-app",
    "parserOptions": {
      "warnOnUnsupportedTypeScriptVersion": false
    }
  },

But the error message still shows on npm start. Any idea why this didn’t work?
