Alas, Team Foundation Server is not supported in Microsoft Q&A. TFS/DevOps have their own forum somewhere, which I don't recall on the top of my head. I guess Google can help you.

The solution to this issue is described here: https://learn.microsoft.com/en-US/troubleshoot/azure/devops/error-add-link-work-item
However, it mentions the product TFS 2017 only. Is this still supported with the most recent version of Azure Devops Server?
Also, I was under the impression that Microsoft did not support direct modifications to the SQL database for ADO. Is this solution recommended now?
