TypeError: fetch is not a function

[arnaudjnn]

I have the following error when using a Next.js new app router API route.

TypeError: fetch is not a function (same error for each provider)

Here is my code (/ap/crypto-convert/route.ts)

import { NextResponse } from 'next/server';
import CryptoConvert from 'crypto-convert';

const convert = new CryptoConvert({
  cryptoInterval: 60 * 1e3 * 60, //Crypto prices update interval (every 1 hour)
  fiatInterval: 60 * 1e3 * 60, //Fiat prices update interval (every 1 hour)
});

export async function GET() {
  await convert.ready();

  const currencyConversions = convert.USDC.USD(1)

  return NextResponse.json(currencyConversions, { status: 200 });
}
