Error with function <> when opening elementor shortcode

I’m getting an error message anytime I try to get back to a generated elementor shortcode to edit the element.

1. I generate a new elementor shortcode editing an elementor element (a button in this case) through the shortcodes for elementor plugin
2. I can use it properly
3. when I go back to the elementor page of the element of the shortcode I get the message that the page cannot be open (so I cannot edit it anymore) as the content area in my page hasn’t been found. It says I have to include the function <<the_content>> in the current template for Elementor to work on that page…

How can I fix it?

Thanks
