This seems to be caused by queryRef.toPromise().

I'd love to keep the function in there in the long term, but we might need to ask the React team to make that possible. Meanwhile I'll probably (temporarily?) remove the function.

@phryneas I've been look at the integration with react router https://www.npmjs.com/package/@apollo/client-integration-react-router

It's looking pretty good, but can see that queryRef.toPromise() has been disabled.
Looking at the comments it seems this was disabled due to issues with RSC. Was this problem specific to the next js integraton. And is it possible to bring this feature back so it could be used with react router 7?

[phryneas]

We might be able to bring it back, but really it depends if we can somehow hide it from React-Router's serialization.

As that might be difficult, we might also need to create a completely different API for that, so maybe something like preloader.toPromise(queryRef).
