Author ID mistaken with node id
In the EVA Field display of the View you'll see a section there called "Entity content settings." Make sure the settings there are as follows:


a. Entity type: Node
b. Bundles: select the event type content type that you want to appear at the bottom.
c. Arguments: Choose: "Use tokens from the entity the view is attached to" and then add the following token (with brackets) where it asks for the token: [node:author:uid]


Now set the contextual filter for the EVA field display as follows:
Author uid
with the following setting: 
Provide default value: User ID from URL.
Optionally, if you want to include something like "Events created by Jane Smith" at the top of the EVA view, then you need to add a relationship to the User. Then in the "Fields" section add user name and set it to "Exclude from display." Create a header for the view and choose "Global text" and check on the functionality to allow the use of tokens in the text. The user name token will be [name].


That's it. You'll be good.

I think it is worth to note what's a bit confusing here. It might help you to remember next time.
a. "User ID from URL" is really a misnomer. It's getting the User id from the node. The user id is not in the URL at all.
b. It feels like the filter/argument is being set twice; once in the Entity settings and then again in the Contextual filter settings.
