Need some help baking, "No active image found in material" I followed the guide here: How do I bake a texture using Cycles bake

I unwrapped my UV, created a new image, created an Image Texture node and selected my new image with that, and hit bake. I then receive the error in the title. Here is a screenshot of my view:


I'm definitely doing something wrong, hopefully one of you can point out what that is.
For baking in cycles each material slot requires image texture in the node setup, and it looks like even if the material slot is empty. To fix the error, remove the empty material slot from the object.
