Exception while Reverse replication of the comments | Unable to purge old items

[Lalit_Saini]

Hi All,

I am trying to use the HBS comments component present in communities component group on a page to check the comments functionality and getting below exception. I have tested that reverse replication agent is working fine and configured properly. Can anyone help if they have faced this issue before

Hi Lalit,

I'm going to move this to the AEM Communities forum.

While I do so, I'll provide you with this information.

If you're using AEM 6.0 social communities, are you able to upgrade to AEM 6.2 Communities?  or AEM 6.1 Communities?

If you're already using 6.1 or 6.2, then there is no need for reverse replication.  You should read Community Content Store (commonly referred to as SRP).

If you've read about SRP and still feel you need to reverse replicate, would you please provide more details of your deployment and why you feel the need to do so?

We are using AEM 6.0 with SP1. We only require the comments section on the page which can be moderated

For that we used comments component provided in communities component group. Currently upgrade is not in our roadmap ,without Upgrading it to 6.1 or 6.2 is there a way make it work.

Hi Lalit,

I have not yet found reference to this as a known issue.

Before moving forward, would you apply the latest service pack, SP3, and ensure you have the latest Communities fix pack, 1.5.171?

For more information, visit the AEM 6.0 hot fixes page.  

Then install the Community Components Guide and see if reverse replication and moderation work for the comments component found in the guide.

If this is not helpful, please contact Customer Care and open a support ticket.

Release notes for SP3 are here : https://docs.adobe.com/docs/en/aem/6-0/release-notes-sp3.html

You can install SP3 directly on SP1 - you don't need to install SP2 first.

While platform service packs do not affect the Communities package, it is still recommended to install AEM 6.0 Social Communities Fix Pack v1.5.171 after installing SP3.
