Exact steps to cause this issue

Look into Google Search console or use their rich data tool to directly check a topic, e.g. https://search.google.com/test/rich-results/result/r%2Fdiscussion-forum?id=HeHDbDMe_4T8uXKPIZWRgg

What you expected

For google to correctly parse the structured data

What happened instead

Google throws multiple errors. Primary issues:

• comment author has invalid name field (should be Text. I think according to spec the URL should be serialized, but I guess Google didn't bother)
• DiscussionForumPosting is missing datePublished and author fields
• initial post should have text/image/video specified

There's also a warning for missing url property, and the tool mentiones that optionally comments could be listed in CreativeWork objects.

Anything else?

Even if Google is in the wrong about specs, NodeBB should probably follow Google here...
