Unable to use SDK in Vercel serverless environment due to proxy-agent dependency.

• I have checked that the SDK documentation doesn't solve my issue.
• I have checked that the API documentation doesn't solve my issue.
• I have searched the Box Developer Forums and my issue isn't already reported (or if it has been reported, I have attached a link to it, for reference).
• I have searched Issues in this repo and my issue isn't already reported.

Description of the Issue

I've built a NextJS app and have included the Box SDK within some API routes. These routes work locally and also from a clean GitPod environment. When the NextJS route is deployed to Vercel, I receive the following error when trying to execute any of the API routes that include Box SDK.

Steps to Reproduce

1. Create a NextJS starter project and place the lines of code below in an API route folder. This example is for demonstratable purposes only. Get Started with NextJS

import {
  BOX_CLIENT_ID,
  BOX_CLIENT_SECRET,
  BOX_CONTRACT_TEMPLATE_ID,
  BOX_ENTERPRISE_ID,
  BOX_USER_ID,
} from '@/constants'
import { BoxCcgAuth } from 'box-typescript-sdk-gen'

export async function GET(
  req: NextRequest
) {
  try {
    const authClient = new BoxCcgAuth({ config: this._config });
    const tokenResponse = await authClient.withUserSubject(BOX_USER_ID as string).retrieveToken()
    return NextResponse.json({ success: true }, { status: 200 })
  } catch (e) { return NextResponse.json({ success: false }, { status: 400 }) }
}

3. Deploy to Vercel.com with the free plan
4. Call the API from Postman

Expected Behavior

You should receive a 200
