# Look rotation viewing vector is zero in Unity when making UI

How can I tackle the problem: Look rotation viewing vector is zero?

Here is how I get it:

1. I add an Image from UI.

2. When the Image is added I click on it in the Hierarchy view.

3. When focus is on an Image I take the Canvas border and move it left.

4. I get the Exception.

Here are some screenshots of the process which takes place:

In the last screenshot I selected the Canvas and tried to focus on it by pressing F in the Scene view. As you can see I am not able to resize the canvas anymore. That means that I would have to create a new Canvas and copy everything into it, which is pretty tiresome and error prone. That is a reason I am concerned with the Exception. Will appreciate any attention.
