Agent service not available in West Europe due to lack of support for Vector stores

Technical Feedback

Hi!

This is partly related to this discussion, but whereas that is related to the Vector stores and its use File Search tool, this is about Vector stores as a fundamental dependency of the Agent Service itself, and how a lack of support for Vector stores in West Europe renders this region unavailable for Standard Agent deployments.

According to the Foundry documentation link West Europe is supposed to be a supported region for most models below gpt 5, e.g. a gpt-4.1 or gpt-4o, using deployment type "Global standard".

Yet, when I deploy to this region using one of the bicep templates found in the Github repo, the one for Standard agent with Public Networking link, after the deployment has succeeded, the Portal (classic) will show a red warning on top of the Agents view stating "Unable to fetch vector stores".

Using the REST API to send a request to {endpoint}/vector_stores/?api-version=v1 will yield a 400 Bad request for a West Europe deployment, with a "Vector stores are not supported in this region." message, while the same request to e.g. a Norway East deployment will yield a 200 OK.

The only place in the documentation I can find a reference to a Vector store is the File Search tool. I am not planning to use that, and it was not part of the template deployment, but apparently the vector stores are also fundamental to the Agent service itself, not only to the File Search tool.

The company I work for has a VNet integration in West Europe only, so simply selecting Sweden Central or US East 2 is not an option, unfortunately.

Are you aware of this limitation, and that because of this, region West Europe is actually not available for the Standard agent setup, in contradiction with what's written in the documentation?

Desired Outcome

The same support for Agent Service in West Europe as in most other regions, in other words: Make Vector stores available in West Europe.

Current Workaround

None, since company VNet integration and policies demand using region West Europe.
