I have recently been doing a TFS 2015 to Azure DevOps Server 2019.1 upgrade for a client. The first for a while, I have been working with Azure DevOps Service mostly of late. Anyway I saw an issue I had never seen before with any version of TFS, and I could find no information on the Internet.
The Problem
The error occurred when I tried to queue a new build after the upgrade, the build instantly failed with the error
‘The module being executed is not trusted, Either the owner of the database of the module need to be granted authenticate permission, or the module needs to be digitally signed. Warning: Null value is eliminated by an aggregate or other SET operation, The statement has been terminated’.
The Solution
It turns out the issue was the the client was using a enterprise wide SQL cluster to host the tfs_ databases. After the Azure DevOps upgrade the DBAs has enabled a trigger based logging system to monitor the databases and this was causing the error.
As soon as this logging was switched off everything worked as expected.
I would not recommend using such a logging tool for any ‘out the box’ database for a product such as TFS/Azure DevOps Server where the DBA team don’t own the database schema’s changes, as these databases will only occur if the product is upgraded
