This fixes the msteams probe which otherwise incorrectly assumes teams is not working.
The @microsoft/agents-hosting SDK's MsalTokenProvider automatically appends /.default to all scope strings in its token acquisition methods (acquireAccessTokenViaSecret, acquireAccessTokenViaFIC, acquireAccessTokenViaWID, acquireTokenWithCertificate in msalTokenProvider.ts). This is consistent SDK behavior, not a recent change.
The current code is including .default in scope URLs, resulting in invalid double suffixes like https://graph.microsoft.com/.default/.default. I am not sure how the .default postfixed worked in the past for you if I am honest.
This was confirmed to cause Graph API authentication errors. Removing the .default suffix from our scope strings allows the SDK to append it correctly, resolving the issue. I confirmed it manually on my teams setup
Before: we pass .default -> SDK appends -> double .default (broken)
After: we pass base URL -> SDK appends -> single .default (works)
