Hello,

Firstly, check the references of this page from the References tab in the left hand side. Check if everything looks okay there.

Secondly, enable a debug log on "com.adobe.cq.xf.impl.ExperienceFragmentsReferenceProvider" and replicate the page again. You should see messages like "Determining references to experience fragments for resource at", "Adding the parent experience fragments as references" etc.

Hopefully, these messages provide more info to understand the cause.

Regards,

Vishu

Question: Are you using the master variation? Have you copied the variation from other XF?

[nikunjj81682294]

Yes. I m using the master variation. It's a new XF getting deployed from the git repo.

Checking the AEM code at "com.adobe.cq.xf.impl.ExperienceFragmentsReferenceProvider"

Page parentXf = getVariationParent(path, resolver);

references.add(new Reference(TYPE_XF, parentXf.getTitle(), parentXf.adaptTo(Resource.class), parentXf.getLastModified().getTimeInMillis()));

It looks like the issue is with one of the properties(title,lastmodified) not set on the fragment/variation.

JaideepBrar​,

I see both the properties cq:lastModified and jcr:title are present on both the master jcr:content and the parent of master jcr:content.

I am still getting the same issue.

[nikunjj81682294]

Deleting the XF and readding it resolved the issue. It was the missing cq:lastModified date.

One More underline point is that If cq:lastReplicationAction is present, then cq:lastReplicated (date value) is must in 6.5 of any JCR node property of that page while publishing from author to live
