context.adapter.getUserToken is not a function

[smokranova]

In the following sample https://github.com/OfficeDev/Microsoft-Teams-Samples/blob/main/samples/app-sso/nodejs/server/bots/botActivityHandler.js it seems that the context.adapter should be of type BotFrameworkAdapter, however it appears to be of type CloudAdapter, which means getUserToken and getSignInLink in the function handleTeamsMessagingExtensionFetchTask throw an exception. Is there a version of these functions that works with CloudAdapter or a different way to authenticate within a message extension?

@smokranova - Please have look into this sample-https://github.com/OfficeDev/Microsoft-Teams-Samples/blob/main/samples/bot-conversation-sso-quickstart/js/index.js#L34

const adapter = new CloudAdapter(botFrameworkAuthentication);
server.post('/api/messages', async (req, res) => {
    // Route received a request to adapter for processing
    await adapter.process(req, res, (context) => bot.run(context));
});

Also refer the document for the Cloud Adapter class-https://learn.microsoft.com/en-us/dotnet/api/microsoft.bot.builder.integration.aspnet.core.cloudadapter?view=botbuilder-dotnet-stable

Hi, thanks for your answer. I have seen both of the things you linked while looking for an answer, however neither quite helps me with how to get the token or sign in link

Hope it is helpful.

                var state = action.State; // Check the state value
                var tokenResponse = await GetTokenResponse(turnContext, _botConnectionName, state, cancellationToken);

                if (tokenResponse == null || string.IsNullOrEmpty(tokenResponse.Token))
                {
                    // There is no token, so the user has not signed in yet.

                    // Retrieve the OAuth Sign in Link to use in the MessagingExtensionResult Suggested Actions
                    var signInLink = await GetSignInLinkAsync(turnContext, _botConnectionName, cancellationToken).ConfigureAwait(false);

                    return new MessagingExtensionActionResponse
                    {

                            Type = "auth",

                                        Type = ActionTypes.OpenUrl,
                                        Value = signInLink,
                                        Title = "Bot Service OAuth",
                                    },
                                },
                            },
                        },

                }

I looked at what you sent and tried it (in nodejs no csharp, but same bot). I still get stuck at the signinlink. I see the SignIn button that is part of the Bot Service OAuth card, however after clicking it I get "Something went wrong, please try again". The sign in url is in the form of "https://europe.token.botframework.com/api/oauth/signin?signin=" and when i open it in a browser it forwards to a page where i can copy some code and it says "Please enter this validation code into the chat window to complete the sign-in:". This does not seem like the desired behaviour of the login flow at all

@smokranova -Here is node sample-https://github.com/OfficeDev/Microsoft-Teams-Samples/tree/f7779e42022176c3ae807e4e23acf0d0479c6c39/samples/app-complete-auth/nodejs

Also please have look into this document to add the authentication to teams bot-https://learn.microsoft.com/en-us/microsoftteams/platform/bots/how-to/authentication/add-authentication?tabs=dotnet%2Cdotnet-sample#prerequisites

Hi, my issue in the last bit ended up being that the valid domain in the manifest needed to be "europe.botframework...". now it all finally works, thanks!
