If you are using .net, then in your create payment api call, return an object that contains the order id instead of returning the BraintreeHttp.HttpResponse

 [HttpPost]
    public async Task Post()
    {
        try
        {
            var request = new OrdersCreateRequest();
            request.Prefer("return=representation");
            request.RequestBody(BuildRequestBody());
            //3. Call PayPal to set up a transaction
            var response = await PayPalClient.client().Execute(request);
            Order order = new Order();
            var result = response.Result();


            if (result?.Status?.Trim()?.ToLower() == "created")
            {
                order.OrderId = result.Id;
            }

            return order;
        }
        catch (Exception ex)
        {
            string m = ex.Message;
            throw;
        }
    }

then on my js

 paypal.Buttons({
        createOrder: function () {


          return fetch('/api/paypal', {
            method: 'post',
            headers: {
              'content-type': 'application/json'
              }
          }).then(function(res) {
            return res.json();
          }).then(function (data) {
            return data.orderId; // the data is the order object returned from the api call, its not the BrainTree.Response object
          });
        }

Sorry for sloppy code, I was still in the process of trying to figure out the problem. Hope you get the gist of the solution
