The report is attempting to retrieve a certification entity that no longer exists in the database. This typically occurs when the certification ID referenced by the report has been deleted or is otherwise missing.
Check the database to confirm whether the certification ID referenced in the report still exists. If the ID is missing, determine whether it was deleted intentionally or due to an error.
Rerun the report using a current or recent campaign tag to ensure it processes correctly without throwing errors.
Yes, Certification entity referenced in the error is not present in DB. And every time during the report error certification entity ID is different. The ID is not same. If we run the same report with grouping 4-5 tags at time is working fine, but if we run all at once is failing. so please help us how we can fix this issue.
