Object at Focus of convex lens

I see some web saying that for object placed in the focus the image formed will be at Infinity, highly magnified, and inverted . While some web says "No image will be formed"

Which one is true?

Both are correct.

The image would be formed at infinity which cannot be caught on the screen.
