Is any a good default? Should it be a string?

That was the original rub, that the defaultResolverAsync returned a promise and not a string. Here's a playground I threw together, and I'm not sure how to specify anything other than any here. (I tried unknown and string | Promise<string>)

A resolver should always return a string or null (from memory, I can very tomorrow)

Even an async resolver? Wouldn't it return a promise?

Seems like that would work, yeah. Here's a version that's a bit more strict and expects string or null (or promise of one) to be returned from the resolver https://tsplay.dev/mA2Z8W

Though in the end, I wonder if this should really care what the resolver returns. So maybe your version is better.

request: string,
options: JestResolverOptions<D>
): ReturnType<D>
