Module parse failed: Unexpected token walletconnect-v2

[MHarisAshfaq]

Node Version is v14.21.2

This is my package.json file:

  "name": "my-app",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.14.1",
    "@testing-library/react": "^13.0.0",

    "@types/node": "^16.7.13",

  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

And this is the error I am facing

Failed to compile.

./node_modules/@walletconnect/ethereum-provider/dist/index.es.js 55:10

File was processed with these loaders:

This error show up when I run npm/yarn start

I see that you are using Create React App, I ended up using Craco and added the appropriate babel loaders such as optional chaining and null coalescing.
