Client not returning event error

[taylorcenters]

I have a before_node_update EventHandler that will return an error if certain conditions are met. In this case checking if a node with the same name exists already.

                    if name_exists.is_empty() {
                        return Ok(value);
                    }
                    else {
                        return Err((crate::Error::ProjectNameExists).into());
                    }

I'm using the warpgrapher client to test the feature, however the result coming back from the client in the error case the Result option is not the Error that I am returning, instead it is serde_json::Value::Null returned

In this test, the Project node with the name "Apollo" already exists, so I expect the result to be an Error.

    let result = client
        .update_node(
            "Project",
            "id",
            None,
            Some(&json!({
                "name": {"EQ": "Achilles"},
            })),
            &json!({
                "name": "Apollo",
            })
        ).await;
    println!("{:#?}", result);

---- test_update_project_duplicate_name stdout ----
Ok(
    Null,
)

should have noted that the error gets returned properly to other graphql client

{
  "data": {
    "ProjectUpdate": null
  },
  "errors": [
    {
      "message": "Event handler returned an error: ProjectNameExists",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "ProjectUpdate"
      ]
    }
  ]
}
