Cannot retrieve data from PublishingPageContentOWSHTML in a Content Search Web Part

Question

I tried to display the content of a page using Content Search Web Part, the page is stored in a Pages library and the content type is Article Page.  When the data is retrieved in the Content Search Web Part, the page content mapping to PublishingPageContentOWSHTML
is empty, although other data, such as Title and Page Image, can be retrieved.  It's very strange that I can do this work correctly for another CSWP web part, that page is stored in a Pages library in another subsite.  Both of the CSWP web parts
are on the same publishing site.
Could everybody tell me what I was doing wrong?   Thanks you very much in advance.

Hi Albert GSC, I had the same problem. I'm starting now with display templates and after including "'SecondaryFileExtension','ContentTypeId'" at the end of the mso:ManagedPropertyMapping section it worked.
For example, my mso:ManagedPropertyMapping section was (PublishingPageContentOWSHTML returns empty):
<mso:ManagedPropertyMapping msdt:dt="string">
'Picture URL'{URL de la imagen}:'PublishingImage;PictureURL;PictureThumbnailURL',
'Link URL'{Dirección URL del vínculo}:'Path',
'Line 1':'ArticleStartDateOWSDATE',
'Line 2':'Title',
'Line 3':'PublishingPageContentOWSHTML'
</mso:ManagedPropertyMapping>
Then I included "'SecondaryFileExtension','ContentTypeId'" (PublishingPageContentOWSHTML returns its value):
<mso:ManagedPropertyMapping msdt:dt="string">
'Picture URL'{URL de la imagen}:'PublishingImage;PictureURL;PictureThumbnailURL',
'Link URL'{Dirección URL del vínculo}:'Path',
'Line 1':'ArticleStartDateOWSDATE',
'Line 2':'Title',
'Line 3':'PublishingPageContentOWSHTML',
'SecondaryFileExtension','ContentTypeId'
</mso:ManagedPropertyMapping>
Still don't understand why but I'm looking for the reason, until then hope it helps
