SQL error Violation of PRIMARY KEY constraint

[HugsNotDrugs]

Hello, does anyone have an idea what might be causing on how to fix error:

"Failed: Failed to do rollup from  - Violation of PRIMARY KEY constraint. Cannot insert duplicate key in object . The duplicate key value is "

It stated happening for one of my data rolloup server task recently. I noticed there are some entries in the community about this particular problem in the past but with no clear solution

Hello, 

Reason why this issue is happening sound to be clear from the error message. Now we need to know what exactly the value is and from which table it comes from. I would suggest to open a ticket with support to investigate this issue further. 

You can try purging the data from roll-up and performing a new roll-up and see if the problem still remains.
