This Google Analytics API error means that the selected advanced segment is not available to the account you are using. This usually happens when you share a report with a coworker.
Advanced segments in Google Analytics are personal assets and are associated with your login account. If you want to share a custom segment with others, see this Google Analytics help article.
Alternatively, with the Analytics Edge connectors for Google Analytics, you can add the segment as a dynamic segment in the query. Dynamic segments are independent of the accounts and are saved in the workbook with the query.
