What is the correct way of filtering by a nullable property?

[brielov]

Given the following schema:

type Post {
  required property title -> str;
  property published_at -> datetime;
}

How can I query (using the typescript query builder) all posts that have published_at set?

// Get all posts that have `published_at` set with a datetime.
const query = e.select(e.Post, (post) => ({
  title: true,
  filter: /** post.published_at is not nullish */
})

Use exists:

const query = e.select(e.Post, (post) => ({
  title: true,
  filter: e.op('exists', post.published_at)
})

I'm feeling quite stupid right now 🥲. Thank you so much for the quick response.
