fix: `TypeError: can't convert BigInt to number`

[cromatikap]

After the following

$ npx create-react-app my-safe-app --template @safe-global/cra-template-safe-app
$ cd my-safe-app
$ npm i
$ npm run build

The build would display a blank page with TypeError: can't convert BigInt to number error in console.

I applied this solution and it fixed the issue.
