{"error":{"code":"Unspecified","message":"Internal server error"}}

same issue described here,

https://learn.microsoft.com/en-us/answers/questions/5996139/get-client-access-token-for-face-api-fail-with-cod

I can not get access token using this API GET {endpoint}/face/{apiVersion}/settings/getClientAssetsAccessToken to fetch https://github.com/Azure/AzureAIVisionFaceUI . It return a response like this {"error":{"code":"Unspecified","message":"Internal server error"}}
I can get it before but It is not working since 04/09/2026

Start with the Microsoft Q&A report and reproduce the GET request to {endpoint}/face/{apiVersion}/settings/getClientAssetsAccessToken described in the issue. Compare the current response with the previously working behavior and document whether the endpoint returns a usable access token instead of the reported internal-server-error response.
