SSO fails at Invoke signin/verifyState

New Contributor

Following scenario: I have a working bot with an AAD v2 OAuth connection. Now i have created a new bot which is just for staging (DEV/PROD). This new bot works the same with one exception: SSO in MS Teams. Magic Code authentication works in both MS Teams and Emulator. SSO only works in Emulator. The error is the following:


Invoke failed due to internal error: Invoke failed: something went wrong in ProcessInvoke


This error occures when MS Teams sends the signin/verifyState Invoke Message to and results in a HTTP 500...

Since the SSO directly to my new bot does work in the Bot Framework Emulator i am sure this problem is on the site


Both bots are configured in the same way. The only difference is the MS App ID and Password. This issue is a showbreaker for us, since we cannot use MS Teams if there is no SSO supported.

The Team around MS Teams seems to have fixed the issue. It is still not perfect but you can read about it here:
