Why the Unity is displaying this message : "ArgumentException: Input Button Submit is not setup" in console when I run my scene

Hi, this is my first question in this forum and I would clarify a question, ever when I run my start menu scene in Unity, the same display this message:

ArgumentException: Input Button Submit is not setup.
 To change the input settings use: Edit -> Project Settings -> Input
UnityEngine.EventSystems.StandaloneInputModule.ShouldActivateModule () (at C:/buildslave/unity/build/Extensions/guisystem/UnityEngine.UI/EventSystem/InputModules/StandaloneInputModule.cs:137)
UnityEngine.EventSystems.EventSystem.Update () (at C:/buildslave/unity/build/Extensions/guisystem/UnityEngine.UI/EventSystem/EventSystem.cs:250)

Somebody know to tell me why happen it

This happened to me when I removed everything from the project settings - input. (because I want to use a different input method)

I solved it by adding Submit, Cancel, Horizontal and Vertical to the input settings.

Go to input settings use: Edit → Project Settings → Input
There is a little cog wheel in the corner which will reset the input settings.
After i pressed it the error went away.

If you don’t use Submit, Cancel etc., you can add an empty entry into InputManager and your error will be fixed.

Alright. So if you look at the error message, it tells you exactly why it’s happening, and even how to fix it.

What’s wrong here?

Input Button Submit is not setup.

How do you fix it?

To change the input settings use: Edit -> Project Settings -> Input
