• Microsoft.Bot.Builder.Integration.AspNet.Core 4.19.3 4.19.3

Describe the bug

The endpoint https://api.botframework.com/api/botsignin/GetSignInResource intermittently fails and returns a 404 with this message:

{"error": {"code": "ServiceError","message": "Bot does not exist"}}

To Reproduce

I created a project based on the teams authentication sample. The bot tries to ask the user for authentication using the OAuthPrompt.SendOAuthCardAsync method. The endpoint fails ~95% of times. Sources and extra info here.

Expected behavior

The endpoint succeeds a few times a day. Meaning the request might be okay. I think the endpoint has a problem.

Additional context

I created this stackoverflow post: BotFramework-Teams-Authentication issue GetSignInResource fails often but it says that stackoverflow is more for “how-tos”. Considering the problem is a bug, I think it is better to post it here.
