Okx getBalance causing Cannot convert a BigInt value to a number for npm build

Occurs after running npm run build and using OKx to getBalance. Producing the following:

  Uncaught (in promise) TypeError: Cannot convert a BigInt value to a number

I am working on a browser extension using react, so I run npm run build and then load the extension into edge. This error doesn’t occur when using npm start and also occurs on older versions.

Seems its browser compatibility settings for production. Using the following in package.json resolved it:

"browserslist": {
    "production": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }

Thank you for the assistance.

It’s not really an issue with the CCXT code, it’s more like an issue with how create-react-app treats JavaScript’s operators:
