Unable to publish a page after SP14 upgrade

[narayana_chirra]

Hello,

We are upgrading to AEM 6.5 with SP14 from SP7. After upgrade Pages are not publishing (quick publish, Mange publish or direct publish from edit page).

We are unable to reproduce this issue in local instance, only happening on actual servers.

Shown below seeing ERROR Failed to retrieve references for the selected page. Anyone else is facing similar issue with SP14 upgrade.

I have noticed below error in the error.log

org.apache.sling.jcr.resource.internal.JcrSystemUserValidator The provided service principal name 
'commerce-reader-service' is not a known JCR system user id and therefore not allowed in the 
Sling Service User Mapper.

 Based on that I have created system user "commerce-reader-service" then it started working
