Error: Conversion from 'BigInt' to 'number' is not allowed on react build script

Question

I've developed UI using create-react-app. UI is working fine with the normal npm start command, but when I build the UI with npm run build it's throwing the error `Conversion from 'BigInt' to 'number' is not allowed

I didn't get many related solutions to my problem on google. Can someone help please ?

My Package.json

Please try this.

In your package.json.

"browserslist": {
    "production": [
      "chrome >= 67",
      "edge >= 79",
      "firefox >= 68",
      "opera >= 54",
      "safari >= 14"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }

Don't know what is the root cause but it will works. It comes from here
