According to the official Next.js documentation on [Environmental Variables](https://nextjs.org/docs/basic-features/environment-variables): 
> `process.env` is not a standard JavaScript object, so you’re not able to use object destructuring. Environment variables must be referenced as e.g. `process.env.NEXT_PUBLIC_PUBLISHABLE_KEY`, not `const { NEXT_PUBLIC_PUBLISHABLE_KEY } = process.env`.
