Error "Ambiguous class, provide a unique identifier" with next.js 10.0.6

[flybayer]

We are having an issue with next.js 10.0.6 in Blitz where we get the "Ambiguous class, provide a unique identifier" error even though all classes have unique ids.

Possible fix:

Disable this check, https://github.com/blitz-js/superjson/blob/main/src/registry.ts#L17, if you are explicitly providing an identifier.
