missing "URL" field - (QAPage)

[medelinor-1]

Hi, I hope you are all well

When I check the discussion page using the URL Inspection tool in Google Search Console, it seems that there is a missing field, It is about the "URL" field. and the problem is not critical.

However, fixing it may improve the feature's visibility in search results.

According to Google's documentation, the problem is related to the structured data of the profile pages (ProfilePage). I think it is related to the missing "mainEntity" field in Profile page (ProfilePage) structured data.

Is this an improvement possible?
Thank you very much
