To ID2D1Bitmap a Direct2D ID2D1HwndRenderTarget.

I need to convert a Direct2D ID2D1HwndRenderTarget into an ID2D1Bitmap.
However, I’m encountering an error with CopyFromRenderTarget.
”Error: E_INVALIDARG One or more arguments are invalid.”

What could be the issue?

using Direct2D 1.0 (include d2d1.h)

　　// ID2D1HwndRenderTarget* target 

    HRESULT hr;
    D2D1_SIZE_F size = target->GetSize();
    UINT width = static_cast< UINT >( size.width );
    UINT height = static_cast< UINT >( size.height );

    D2D1_SIZE_U px_size = target->GetPixelSize();
    
    D2D1_BITMAP_PROPERTIES props;
    bitmapProperties.pixelFormat = D2D1::PixelFormat( DXGI_FORMAT_B8G8R8A8_UNORM, D2D1_ALPHA_MODE_PREMULTIPLIED );
    bitmapProperties.dpiX = 96.0f;
    bitmapProperties.dpiY = 96.0f;

    ID2D1Bitmap* src_bitmap;
    hr = target->CreateBitmap( px_size, NULL, 0, &props, src_bitmap );

    // Copy the contents of the current drawing target to a bitmap
    D2D1_POINT_2U destPoint = D2D1::Point2U( 0, 0 );
    D2D1_RECT_U srcRect = D2D1::RectU( 0, 0, px_size.width, px_size.height );

    // Error: E_INVALIDARG One or more arguments are invalid.
    hr = src_bitmap->CopyFromRenderTarget( &destPoint, target, &srcRect );
