DataOf not really working?

I'm trying to use DataOf on a project, and TypeScript keeps resolving everything to `any`.

For example, I have:
```
requestBody: z.object({
address: z.string(),
chainId: z.string(),
token: z.string(),
}),
```

And then I do:
```
data: DataOf
```

But the resolved types are always:

Start by reproducing the TypeScript inference issue with the provided requestBody schema and `DataOf` example. Inspect the definition and uses of `DataOf` and compare the inferred result with the schema; done means the resulting fields are no longer resolved to `any`.
