If a query/mutation returns an Err, how do I access it at the top level?

[mikebaldry]

I want to log any errors like this. but using code like:

    let query: GraphQLRequest = request.body_json().await?;
    let response = query.execute(&SCHEMA, request.state()).await;

    let status = if response.is_ok() {
        StatusCode::Ok
    } else {
        StatusCode::BadRequest
    };

    Ok(Response::builder(status)
        .body(Body::from_json(&response)?)
        .build())

I am unable to access anything on response as the actual Result is not public.

Can anyone suggest how this should be achieved?

@mikebaldry could you share your use case? Why do you need it at all?

At the moment, this can be achieved in the following ways:

• Serialize GraphQLResponse as serde_json::Value and inspect it.

• Do not call GraphQLRequest::execute(), but rather juniper::execute() directly, so you will receive a raw Result instead of GraphQLResponse. This requires either your own struct to deserialize GraphQL request in the manner of GraphQLRequest, since on juniper 0.15 GraphQLRequest doesn't expose it inners, or you can just switch latest master and deserialize into GraphQLRequest as you do:

  let request: GraphQLRequest = request.body_json().await?;
  let result = juniper::execute(
    &request.query,
    request.operation_name.as_deref(),
    &SCHEMA,
    &request.variables(),
    full_request.state(),
  ).await;
  let response = GraphQLResponse::from_result(result);
  
  let status = if response.is_ok() {
    StatusCode::Ok
  } else {
    StatusCode::BadRequest
  };
  
  Ok(Response::builder(status)
    .body(Body::from_json(&response)?)
    .build())

Thanks for the swift response. My use case, I don't think is anything special. I just want to log any errors that occur so I can report on them or find more details than what would be exposed via the graphql output.
