Undefined variable $args

I am getting the following error on my website:
Warning: Undefined variable $args in /home/dcvytn7gq6hh/coloradobirthservices.com/wp-content/themes/agama/framework/admin/kirki/packages/kirki-framework/compatibility/src/Kirki.php on line 175

I have found this line, but I have no idea what to do with it or how to fix it.

Lines 165 to 178:

/**
	 * Remove a section.
	 *
	 * @static
	 * @access public
	 * @since 3.0.17
	 * @param string $id The ID for this section.
	 */
	public static function remove_section( $id = '' ) {

		$section = new \Kirki\Section( $id, $args );
		$section->remove();

	}
