VideoObject schema present but missing required fields

VideoObject is schema describing a video, and Google requires a specific set of fields, name, description, thumbnailUrl and uploadDate, before it will consider a video eligible for its video rich result (the enhanced search listing with a visible thumbnail). This check found your VideoObject schema present but missing one or more of those required fields. Incomplete VideoObject schema is treated the same as no schema at all for Google's video rich-result eligibility check, so the video gets none of the visibility benefit even though the markup technically exists on the page. It's an easy gap to miss because the schema block looks complete at a glance. Your developer needs about 30 minutes. Fill in whichever required fields are missing: thumbnailUrl must point to a real, absolute image URL (not a relative path), and uploadDate must be in ISO 8601 date format. Re-run Google's Rich Results Test afterwards to confirm the video now qualifies for the rich result.
