When I click "Get Videos" in the Oovvuu plugin, I get an error saying "Cannot read property ‘wordings’ of null."

This error is returned when an article is unusually long, and it returns more keywords or phrases than Oovvuu was expecting. This error only occurs in early versions of the Oovvuu platform. A solution was deployed in mid-2020, so downloading the latest version of the Oovvuu plugin will fix it.
