How can i fix that

Hi @IlyaZhuravlev,

Welcome to Developer Community. The document you linked to is specifically for PostgreSQL and errors in Active Objects table which isn’t what it looks like here as you’re referring to the issuelink table.

What I think is happening is you’re trying to link an issue, the table issuelink already has data, but the sequence for generating the values for the ID column needs to be reset to be greater than the max value of the table. However, the table doesn’t have a separate sequence.

This document might be of more help

Specifically, you’re looking for IssueLink entry in sequence_value_item.
