INVALID_IMAGE_FORMAT_DESCRIPTOR

[gybo03]

case 1)
image = np.array(Image.open(image_path).convert("RGBA"))
image_buf = cl.image_from_array(context, image, 4)
case 2)
image = np.array(Image.open(image_path).convert("RGB"))
image_buf = cl.image_from_array(context, image, 3)

for context this is shape of an array:
image = np.array(Image.open(image_path))
image.shape=(h,w,3)

case 1 works fine without error but case 2 gives back the error:
pyopencl._cl.RuntimeError: clCreateImage failed: INVALID_IMAGE_FORMAT_DESCRIPTOR

in the documentation it is mentioned that rgb is supported i have seen it also in the code of image_from_array(). Im a nooby so i tried finding the Image class to see what i am missing but i couldnt find it. Why does it need that one more byte for alpha, what am i missing. I am using PIL image.
