Validation error trying to copy buffer data to StorageImage

[jonathansty]

I'm trying to copy over some pixel data to an image for usage later on in my pipeline. The problem is that I receive following validation error:

19:33:35 [ERROR] "Object: 0x7ffff67c6108 (Type = 6) | Cannot submit cmd buffer using image (0x7) [sub-resource: aspectMask 0x1 array layer 0, mip level 0], with layout VK_IMAGE_LAYOUT_UNDEFINED when first use is VK_IMAGE_LAYOUT_GENERAL."

I'm using the following code:

let tex = vulkano::image::StorageImage::with_usage(
                device.clone(),
                Dim2d{width: handle.width,height: handle.height},
                Format::R8G8B8A8Unorm,
                ImageUsage{
                    storage:true,
                    transfer_destination:true,
                    ..ImageUsage::none()
                },
                Some(gfx_queue.family())
    ).unwrap();

let buffer = CpuAccessibleBuffer::from_iter(device.clone(), BufferUsage::all(), handle.pixels.iter().cloned()).unwrap();

let command_buffer = AutoCommandBufferBuilder::new(device.clone(),gfx_queue.family()).unwrap()
.copy_buffer_to_image(buffer.clone(), tex.clone()).unwrap()
.build().unwrap();

let finished = command_buffer.execute(gfx_queue.clone()).unwrap();
finished.then_signal_fence_and_flush().unwrap().wait(None).unwrap();
