# Edge Type Does Not Have a Node Type as Its To Source

## Erroneous Code Example

This error occurs when you try to use an edge in a context that requires the `To` type to be a node, but the edge's `To` type is not a node.

<CodeGroup>
  ```helixql queries.hx theme={null}
  QUERY getConnections(id: ID) =>
      user <- N<User>(id)
      connections <- user->LinksTo
      RETURN connections
  ```

  ```helixql schema.hx theme={null}
  N::User {
      name: String,
  }

  V<128>::Document {
      title: String,
  }

  E::LinksTo {
      From: User,
      To: Document,
  }
  ```
</CodeGroup>

## Solution

Ensure the edge type has a node type as its `To` source, or use the appropriate traversal for vector types.

<CodeGroup>
  ```helixql schema.hx theme={null}
  N::User {
      name: String,
  }

  N::Post {
      content: String,
  }

  E::Authored {
      From: User,
      To: Post,
  }
  ```

  ```helixql queries.hx theme={null}
  QUERY getPosts(id: ID) =>
      user <- N<User>(id)
      posts <- user->Authored
      RETURN posts
  ```
</CodeGroup>
