I am receiving notifications from Google that threads which are marked Solved in my forum have validation errors:

Either "acceptedAnswer" or "suggestedAnswer" should be specified (in "mainEntity")

Items with this issue are invalid. Invalid items are not eligible for Google Search's rich results

Is there a plan to fix this issue?

Do you have an example URL where you're seeing this?

This URL was flagged:

https://www.celiac.com/forums/topic/157933-mayonnaise/ 

It looks like as your solution there is actually an embedded URL, this was stripped. I have submitted this internally for review.

This issue has been resolved in our recent 4.7.14 release of the platform. Please upgrade to resolve the issue, and if you see any further problems at that point, please let us know.
