OpenGL FreeImage Texture Loading Error

Question

Currently, my rendering works except for the textures rendering totally black. I am getting the error 1380, or GL_INVALID_ENUM, right after calling glTexture2D in this segment of code. I have tried everything that I can think of, but the error will not go away.

-Calling get error right before this block of code -Texture is in powers of 2 (128 x 128) -Using new 24-bit photoshop .bmp

    glEnable(GL_TEXTURE_2D);

    FREE_IMAGE_FORMAT imageFormat = FreeImage_GetFileType(filename, 0);
    FIBITMAP* bmpImage = FreeImage_ConvertTo32Bits(FreeImage_Load(imageFormat, filename));

    int width = FreeImage_GetWidth(bmpImage);
    int height = FreeImage_GetHeight(bmpImage);
    int nBPP =  FreeImage_GetBPP(bmpImage);

    if (nBPP == 32)
    {
        // Generate an ID for the texture.
        glGenTextures(1, &m_texture);

        // Bind the texture as a 2D texture.
        glBindTexture(GL_TEXTURE_2D, m_texture);

        // Load the image data into the texture unit.
        glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, (GLvoid*)FreeImage_GetBits(bmpImage));

        if(auto temp = glGetError())
        {
            // GL_INVALID_ENUM/1380 here
        }
    }

    FreeImage_Unload(bmpImage);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);

You say the image is 24-bits but in your code you write:

if (nBPP == 32)
