[Bug]: The Bot Framework SDK for C# does not return a value in the Activity.LocalTimezone property when using Copilot in Microsoft Teams

[rfessia]

Language

C#

Version

12

Description

In Microsoft Teams, when we use copilot the Activity.LocalTimezone property (in Bot Framework SDK) has no value, while if we perform a query without using copilot, it returns a value.

In the official Microsoft documentation it says that this property can be used to get the time zone from messages. We need to know the user's LocalTimeZone to make correct filters in our system: https://learn.microsoft.com/en-us/dotnet/api/microsoft.bot.schema.activity.localtimezone?view=botbuilder-dotnet-stable

BUG WHEN USING COPILOT:

1. Messaging extension query USING COPILOT: Send a prompt to copilot in the new Microsof Teams.

2. Check incoming request: There is not localTimezone in the request.

    "queryOptions": { "skip": 0, "count": 10 }
  },

}

3. Check Bot Framework SDK for C#: The LocalTimeZone property in TurnContext is null.

SUCCESSFUL REQUEST WHEN NOT USING COPILOT

1. Messaging extension query WITHOUT USING COPILOT: Send a message extensions in Microsoft Teams.

2. Check incoming request: The localTimezone is present in the request.

    "queryOptions": { "count": 25, "skip": 0 }
  },
  "locale": "en-US",
  "localTimezone": "Pacific/Auckland"
}

3. Check Bot Framework SDK for C#: The LocalTimeZone property has value in ITurnContext :)

P.S., Some values in the request were replaced with "xxx" just for security reasons.

Hello, this issue seems to be with the underlying Bot Framework SDK, which is managed by a different team in a different repository. https://github.com/microsoft/botbuilder-dotnet, I would suggest contacting them to better understand what could be causing the issue.

Hello @aacebo! The Bot Framework SDK team has told us that it is not a problem with the SDK, could you tell us where we should report it? Thank you! https://github.com/microsoft/botbuilder-dotnet/issues/6770
