Running a Next.js app with Growthbook & Chrome Growthbook devtools extension results in an error.

When you setup GrowthBook with the recommended setup from the docs you run into this problem.

Docs I followed:

1. https://docs.growthbook.io/guide/nextjs-app-router#5-integrate-the-growthbook-sdk-into-our-nextjs-app
2. https://docs.growthbook.io/lib/node#nextjs
