Filtering on relations about nexus-prisma

[iddan]

Maybe it should be added to the project roadmap next to relation ordering? https://github.com/prisma/nexus-prisma#midterm

Is there currently any way to filter a relation that's automatically included in the Prisma request? It seems like my include > where clauses are being overwritten by the Nexus plugin and ignored.
Let's say I have a User and Post models and a resolver that does:

const result = await prisma.user.findMany({ where: { userId }, include: { posts: { where: { something: 'impossible' }}}})
console.log(result) // [{ id, ... posts: [] }]
return result

And a query that does:

{
  posts {
    title
  }
}

But the response sent to the client is:

{
  posts: [plenty of posts]
}

How to filter them correctly?

Is there any workaround?
If I change:

t.field(User.posts)

to:

t.list.nonNull.field('posts', { type: 'Post' })

Filtering works correctly.
