[BC] Customcheckout error

I have just cloned the project and set my .env with BC then enabled customCheckout which display an error when clicking on checkout. See the picture bellow

TypeError: Cannot read properties of undefined (reading 'fetcher')

If you try the fix here https://github.com/vercel/commerce/issues/533#issuecomment-981149223 you only just get other errors further down the line. E.g. if you click into Payment Method, you get:

../packages/commerce/dist/utils/use-hook.js (24:0) @ useMutationHook

  22 | export function useMutationHook(hook) {
  23 |     const fetcher = useFetcher();
> 24 |     return hook.useHook({

You also get the same error for Shipping Method.

Getting the custom checkout to actually work therefore just feels like endless whack-a-mole.

I wasn’t able to resolve this, we abandoned Vercel Commerce and went down a different route.
