When flushing the cache on a site recently upgraded to Drupal 8.5, I am now getting a fatal uncaught error:
Rebuilding cache(s), wait a moment please.
PHP Fatal error: Uncaught Error: Call to undefined method Drupal\views\Plugin\views\style\DefaultStyle::getFormats() in /app/docroot/core/modules/rest/src/Plugin/views/display/RestExport.php:368

It's likely this issue predates Contrib.social: some issue and comment data are missing.
In core/modules/rest/src/Plugin/views/display/RestExport.php function collectRoutes
find the line
$formats = $style_plugin->getFormats();
replace with
$formats=false;
if (method_exists($style_plugin,'getFormats'))
$formats = $style_plugin->getFormats();
