unexpected caching when `queryKey` is undefined about query HOT 5 CLOSED

you are right, this doesn't error:

useQuery({
    queryKey: undefined
})

but this does:

useQuery(undefined)

from query.

queryKey is most definitely required on useQuery:

We don't guard against any input that isn't valid typescript

@TkDodo - I think it might be a problem with ^4.x.x, I only get a typescript error in v5.
Maybe patch v4 to prevent undefined queryKey?

can you show a typescript playground please ?

I love not being wrong. :p
it should be as simple as making queryKey non-optional, no?
