We're attempting to setup Buildmaster to have it serve as a deployment and test arm of our builds based on build artifacts.
The connection to TC seems to work. We do get the list of projects from the server.

BM also says that TC has been synchronized.

But when we go to import builds so we can see the artifacts, the dropdown never populates.

What API calls are you using that is supposed to return that info?
TeamCity version is TeamCity Professional 2025.11 Build 207946
and BuildMaster is version Version 2025.5 (Build 14).

We're kind of at a standstill until we can get the artifacts list.
