Connect to App examples don’t work

I'm trying to connect a Ledger Nano S using the example projects on the developer portal.

I have tried the Web USB/HID and the Node HID integration.

Both fail with the error

Cannot read properties of undefined (reading 'decorateAppAPIMethods')

I have tried this on Windows and Linux using the Chrome browser.
The Nano S is unlocked and the Bitcoin app (version 2.1.2) loaded.

Does anyone know what this error means and how I can fix it?
Thanks
