D3D11CreateDeviceAndSwapChain, HRESULT is "Application made an invalid call."?

So, just like the title states, I am setting an HRESULT to D3D11CreateDeviceAndSwapChain with a check to see if it fails. Obviously it does everytime, and when I display the error message by using,

_com_error error(hresult);
LPCSTR errorText = error.ErrorMessage();
MessageBox(hwnd, errorText, "Fatal Error", MB_OK);

The following message is the contents of the MessageBox,

The application made a call that is invalid. Either the parameters of the call or the state of the object was incorrect.

I create my swap chain description using,

DXGI_SWAP_CHAIN_DESC swapChainDesc;
ZeroMemory(&swapChainDesc, sizeof(swapChainDesc));
swapChainDesc.BufferCount                        = 1;
swapChainDesc.BufferDesc.Width                   = screenWidth;
swapChainDesc.BufferDesc.Height                  = screenHeight;
swapChainDesc.BufferDesc.Format                  = DXGI_FORMAT_R8G8B8A8_UNORM;
swapChainDesc.BufferDesc.RefreshRate.Numerator   = 0;  // Numerator and denominator are as they are due to a bug in calculation, leaving me with a number around 760000 while calculating for VSync.
swapChainDesc.BufferDesc.RefreshRate.Denominator = 1;
swapChainDesc.BufferUsage                        = DXGI_USAGE_RENDER_TARGET_OUTPUT;
swapChainDesc.OutputWindow                       = hwnd;
swapChainDesc.SampleDesc.Count                   = 1;
swapChainDesc.SampleDesc.Quality                 = 0;
swapChainDesc.Windowed                           = true;
swapChainDesc.BufferDesc.ScanlineOrdering        = DXGI_MODE_SCANLINE_ORDER_UNSPECIFIED;
swapChainDesc.BufferDesc.Scaling                 = DXGI_MODE_SCALING_UNSPECIFIED;
swapChainDesc.SwapEffect                         = DXGI_SWAP_EFFECT_DISCARD;
swapChainDesc.Flags                              = 0;
featureLevel                                     = D3D_FEATURE_LEVEL_11_0;

And then I attempt to create my swap chain with,

result = D3D11CreateDeviceAndSwapChain(
NULL,
D3D_DRIVER_TYPE_HARDWARE,
NULL,
0,
&featureLevel,
1,
D3D11_SDK_VERSION,
&swapChainDesc,
&m_swapChain,
&m_device,
NULL,
&m_deviceContext);

So my question is, what parameter am I missing or misconfigured that results in this strange error? Thank you for anything in advance.

Note: I have tried changing D3D_DRIVER_TYPE_HARDWARE to REFERENCE with no effect.

Note: If you want to see the whole source code or other useful information that I may have forgotten to mention, it can be found here.

Update: When debugging, I receive this error,

DXGI ERROR: IDXGIFactory::CreateSwapChain: No target window specified in DXGI_SWAP_CHAIN_DESC, and no window associated with owning factory. [ MISCELLANEOUS ERROR #6: ]

This clearly shows that my problem is that the swap chain is not being given a window to attach to and therefore failing. I don't understand why this is happening because in my game class, I initialize the window with,

m_HWND = CreateWindowEx(
    WS_EX_APPWINDOW,
    (LPCSTR)m_AppName,
    "Engine",
    WS_CLIPSIBLINGS | WS_CLIPCHILDREN | WS_POPUP,
    xPos,
    yPos,
    screenWidth,
    screenHeight,
    NULL,
    NULL,
    m_hInst,
    NULL);

And pass the HWND down through functions to get it to the swap chain.

Problem:

While sending the HWND to the CreateDeviceAndSwapChain() function, I had a small mix-up that swapped the original HWND with a different one.

Solution:

After going back and reviewing my code for the fourth time, I found that the mix-up happened in my main frame class, I solved this by removing the secondary useless creation of the other HWND, and fixed the name change between them.

I hope that this post can helps others that receive the error that I got in the post above, as it is merely the swap chain not receiving a working and active HWND. An easy fix but hard to find.
