How to get user details in Bot Framework

Question

I am building a Teams Bot which needs to send out Adaptive Cards to users.

When the bot is installed, i am sending a Welcome message to the user. From the welcome message, i am able to get the user's Teams ID using activity.from.id.

From ID::29:1O_abckkskldjflkjfslxxxxxxxx

With this id, i tried to get the User Details using const member=TeamsInfo.getMember(context, context.activity.from.id);

However I am still unable to get the user details.

How to get the email id of the user so that in future i can send notifications to the user ?

According to the docs, you pass the "id" to getMember only for the dotnet libraries. For Node, it looks like it wants the email/UPN - see here, whereas you're sending activity.from.id. Perhaps try call getPagedMembers instead - if there's only one user (i.e. it's a 1-1 chat), it's effectively the same as getMember.

Working Snippet::

  this.onMembersAdded(async (context, next) => {
            const membersAdded = context.activity.membersAdded;
            for (let cnt = 0; cnt < membersAdded.length; ++cnt) {
                if (membersAdded[cnt].id !== context.activity.recipient.id) {
                    var continuationToken;
                    var members = [];
                    do {
                        var pagedMembers = await TeamsInfo.getPagedMembers(context, 100, continuationToken);
                        continuationToken = pagedMembers.continuationToken;
                        members.push(...pagedMembers.members);
                    } while (continuationToken !== undefined);
                    members.forEach(member => {
                        const userEmail=member.userPrincipalName;
                    });
                    const card = CardFactory.adaptiveCard(welcomeCard);
                    const message = {
                        attachments: [card],
                        summary: 'Welcome'
                    };
                    await context.sendActivity(message);
                }
            }
            // By calling next() you ensure that the next BotHandler is run.
            await next();
        });
