@timneutkens could you have look at this?
Try to see why this error throws.

Great catch. This error is caused when running Next.js on http. localhost has support for serviceworkers for testing purposes. Linking next.dev to 127.0.0.1 in /etc/hosts was enough to reproduce. The best way to handle this is indeed catching the error. Cause it's of no use to us 👍
