Addon causes errors with shortcodes

I am building a site that pulls info from an external API and populates fields and tables to show info to logged in users.

I use a PHP shortcode to hit the API, create a table, populate and display it. I am also using DataTables on the client side to render the tables.

Everything was working fine until I added Essential Addons for Elementor. Now I am getting this error above every shortcode:

Warning: http_build_query(): Parameter 1 expected to be Array or Object. Incorrect value given in /var/www/html/wordpress/wp-includes/Requests/Transport/cURL.php on line 508

Error goes away if I disable the plugin. I have tried re-activating, and also tried disabling all elements within the plugin that I’m not using.

Any idea what could be causing this? I can share the shortcodes that are running as well, if you think that may have something to do with the error (although I was not getting any errors before).
