PHP Error After Inserting the code

I’m having an issue suddenly with pulling in job listings from an API. When I visit the PHPCode page in the admin interface, this error is above the box with all the code: Notice: Trying to get property ‘ID’ of non-object in /home/customer/www/tier4group.com/public_html/wp-content/plugins/insert-php-code-snippet/xyz-functions.php on line 76 When I visit the page where the code is located, https://www.all-for-skin-beauty.com/ I see this error: Parse error: syntax error, unexpected ‘}’, expecting ‘;’ in /home/customer/www/tier4group.com/public_html/wp-content/plugins/insert-php-code-snippet/shortcode-handler.php(97) : eval()’d code on line 47 There has been a critical error on this website. Any thoughts on why? Thanks for the help.
