E_INVALIDARG when calling CreateGraphicsPipelineState

我在调用CreateGraphicsPipelineState()时遇到了一个奇怪的错误。即使描述已经全部设置好，函数也会返回E_INVALIDARG。

之前的描述有效，我试图将indexbuffers添加到我的管道中，我甚至没有接触任何PSO或Shaders的代码，现在PSO的创建完全一团糟。

问题是，在启用调试层时，我没有从驱动程序收到任何DX错误消息。我只得到这个

"Microsoft C++异常：内存位置处的_com_error

当我逐步完成函数时。

这感觉像是指针错误或类似的错误，但我不知道错误是什么。也许你们中的任何人都能看到我犯的明显错误？

这是我的代码：

CGraphicsPSO* pso = new CGraphicsPSO();
D3D12_GRAPHICS_PIPELINE_STATE_DESC psoDesc = {};

// Input Layout
std::vector<D3D12_INPUT_ELEMENT_DESC> elements;
if (aPSODesc.inputLayout != nullptr)
{
auto& ilData = aPSODesc.inputLayout->desc;
for (auto& element : ilData)
{
// All Data here is correct when breaking
D3D12_INPUT_ELEMENT_DESC elementDesc;
elementDesc.SemanticName = element.mySemanticName;
elementDesc.SemanticIndex = element.mySemanticIndex;
elementDesc.InputSlot = element.myInputSlot;
elementDesc.AlignedByteOffset = element.myAlignedByteOffset;
elementDesc.InputSlotClass = _ConvertInputClassificationDX12(element.myInputSlotClass);
elementDesc.Format = _ConvertFormatDX12(element.myFormat);
elementDesc.InstanceDataStepRate = element.myInstanceDataStepRate;
elements.push_back(elementDesc);
}
D3D12_INPUT_LAYOUT_DESC inputLayout = {};
inputLayout.NumElements = (UINT)elements.size();
inputLayout.pInputElementDescs = elements.data();
psoDesc.InputLayout = inputLayout;
}   
// TOPOLOGY
