I am noticing a structured data error in schema-type WebPage which appears to be Jupiter-Generated.
(The property “mainContentOfPage” is not recognized by Google for an object of type WebPage.)
The nature of the error appears to be that the property mainContentOfPage is rendering as structured data with a superfluous set of quotation marks around it. Observe the page’s container div, which renders into:
id="theme-page" class="master-holder clearfix" role=""main"" itemprop=""mainContentOfPage""
Could anyone be so kind as to point us in the direction of the source code which generates this schema type, and a hook which we might use to customize/correct it?
