Child Theme Configurator returning theme php error 1748

[jerryhall]

I generated a child theme using the Child Theme Configurator v2.5.8 plugin on a new install of the theme 'Fruitful' in WP v5.7.2.

After using default settings and clicking the 'analyze' button this message was returned.

The theme "fruitful Child" generated unexpected PHP debug output.

Notice: Trying to get property 'ID' of non-object in /home/customer/www/mydomain.com/public_html/wp-content/themes/fruitful/functions.php on line 1748

The child theme generated no problem.

Thanks!
