jcr:uuid not being generated for pages in AEM Cloud

Recently we are noticing that newly created pages is not having any jcr:uuid associated with it. Is there any way to enable the automatic generation of jcr:uuid for every new page created. It was working fine when we checked last time.

Hi,

The creation of the jcr:uuid is provided by the mixin mix:referenceable. By default, pages won’t have this property so you won't have this by default either.

Auto generating jcr:uuid? There could be tweaks to try to create the jcr:uuid when the page is first created, but I would not recommend this. Instead, use the default ID to identify any node in JCR (the path). If this is not sufficient, i think it’s preferable to come up with a custom solution for generating an ID.

I want to know about the potential reason behind the issue I am facing where uuid is not being generated. Any idea what can be the reason or a fix for this?

Hi @ankan_ghosh

Are you facing this issue in any specific instance/environment or in all environment? If in all environment, were there any changes made after which you started facing this issue?

Only on stage and prod environment. Dev is still generating the uuid after publishing the pages. I build the main branch locally and uuid is being generated in this case as well.
