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

## Erroneous Code Example

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

<CodeGroup>
  ```helixql queries.hx theme={null}
  QUERY getConnections(id: ID) =>
      doc <- V<Document>(id)
      connections <- doc->Related
      RETURN connections
  ```

  ```helixql schema.hx theme={null}
  V<128>::Document {
      title: String,
  }

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

## Solution

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

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

  E::Follows {
      From: User,
      To: User,
  }
  ```

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