Better API to get "BatchResponseContent" error message

After checking whether a batch call has failed or not, I can read the success result as shown in the first part of the following snippet.
But reading the error (else branch) fails.

The following snippet evaluates the result of adding an event to a calendar.

HttpResponseMessage responseMessage = await responseContent.GetResponseByIdAsync(batchStepId);
if (responseMessage.IsSuccessStatusCode)
{
  Event eventResult = await responseContent.GetResponseByIdAsync<Event>(batchStepId);
}
else
{
  ODataError errorResult = await responseContent.GetResponseByIdAsync<ODataError>(batchStepId);
}

Reading the ODataError raises a "Microsoft.Graph.ServiceException: generalException" (instead of returning the "ODataError"), which contains the actual error in the property "RawResponseBody" (in my sample {"error":{"code":"TimeZoneNotSupportedException","message":"A valid TimeZone value must be specified. The following TimeZone value is not supported: ''."}} ).

It works when reading the error like this:

JsonParseNodeFactory parseNodeFactory = new JsonParseNodeFactory();
Stream streamContent = await responseMessage.Content.ReadAsStreamAsync();
var parseNode = parseNodeFactory.GetRootParseNode(CoreConstants.MimeTypeNames.Application.Json, streamContent);
ODataError errorResult = parseNode.GetObjectValue<ODataError>(ODataError.CreateFromDiscriminatorValue);

(found this in https://github.com/microsoftgraph/msgraph-sdk-dotnet/blob/dev/tests/Microsoft.Graph.DotnetCore.Test/Models/ModelSerializationTests.cs)

My suggestion is to add a method GetResponseErrorByIdAsync to "BatchResponseContent(Collection)". Do you consider this reasonable? Or is there a better way to get the error result?

Start with BatchResponseContent and BatchResponseContentCollection, especially GetResponseByIdAsync, to trace how successful and failed batch responses are deserialized. Read tests/Microsoft.Graph.DotnetCore.Test/Models/ModelSerializationTests.cs and use the reported RawResponseBody as the failure case; done means an error response can be retrieved as ODataError through a supported API.
