Can not get category, and reindex now nothing

So, decided to run the /opt/kaltura/bin/, after reading this post:

as our categories existed but were not display, when I ran the command I now get this error:

PHP Catchable fatal error: Argument 1 passed to kSphinxSearchManager::saveToSphinx() must be an instance of IIndexable, instance of CaptionAssetItem given, called in /opt/kaltura/app/deployment/base/scripts/populateSphinxCaptionAssetItem.php on line 33 and defined in /opt/kaltura/app/plugins/search/providers/sphinx_search/lib/kSphinxSearchManager.php on line 532
Failed to run /opt/kaltura/app/deployment/base/scripts/populateSphinxCaptionAssetItem.php.
Please try to run it manually and look at the logs

and now in my Kaltura interface there are no video entries?

I went ahead and modified the code as described here:

@trevor_c thank you so much for providing it, replacing also fixed our issues and the reindex complete. I will see what is the best course of next action is with regard to the file.
