title: How to create a relationship with Neo4j Graphql?
body: <p>Hi I'm in a migration from neo4j-graphql-js.</p>
  <p>Here was my setup, this is the abridged/relevant parts of the definition:</p>
  <pre><code>type Playlist {
      id: ID!,
      name: String!,
      things: [Thing] @relationship(type: &quot;HAS_THING&quot;, direction: OUT),
  }
  </code></pre>
  <pre><code>mutation ADD_THING_TO_PLAYLIST($playlistId: ID!, $thingId: ID!){
    AddPlaylistThings(from: { id: $playlistId }, to: {id: $thingId}){
      to{
        id
      }
    }
  }
  </code></pre>
  <p>And this is what I have now. It returns the proper playlist but things remains empty. <code>relationshipsCreated</code> returns 0.</p>
  <pre><code>
  mutation ADD_THING_TO_PLAYLIST($playlistId: ID!, $thingId: ID!){
    updatePlaylists(
      where: { id: $playlistId },
      connect: { things: { where: { node: { id:$thingId } }}}
    ){
      playlists {
        id
        things {
           id
         }
      }
      info {
        relationshipsCreated
      }
    }
  }
  </code></pre>
  <p>Any idea what may be going wrong and how I should be setting up this <code>connect</code>? It appears correct based on the <a href="https://neo4j.com/docs/graphql-manual/current/guides/migration-guide/mutations/#_connecting" rel="nofollow noreferrer">documentation</a> and lack of errors being spit out at me.</p>
