SiteOrigin Page Builder Won't Save More Than A Single Element

I’m trying to build out a site right now and whenever I add more than one element to the Page Builder, I get the following error:

Fatal error: Cannot use object of type WP_Error as array in /Applications/MAMP/htdocs/mysite/wp-content/plugins/siteorigin-panels/inc/copy.php on line 38

It saves fine when there’s only one element, but it’s as soon as the plugin needs to use an array of objects, that happens.

Line 38 in copy.php is the following:
if($request['response']['code'] == 200 && !empty($request['body'])) $content = $request['body'];
