Bot Framework v4 - initiate chat with a user ( proactive messages )

I would like to start a conversation with a user without that he already chatted with the bot.

I'm proceeding bu getting the conversationId when user install the bot app as mentionned here

Here how I catch reference and serviceUrl by using processActivity event

Then I use continueConversation + reference

const {
    BotFrameworkAdapter,
} = require('botbuilder');
const adapter = new BotFrameworkAdapter({
    appId: "xxxx",
    appPassword: "xxxxy"
})
module.exports = async function(context, req) {
    console.log(adapter);
    try {

        adapter.processActivity(req, context.res, async (turnContext) => {
            const reference = turnContext.activity.conversation.id
            const serviceUrl = turnContext.activity.serviceUrl

            await adapter.continueConversation(reference, async (turnContext) => {
                try {
                    await turnContext.sendActivity("this is proacive message");

                } catch (e) {
                    console.log(e)
                }
            });

        });
    } catch (e) {
        console.log(e)
    }
    return;
};

I'm getting this error

Error: BotFrameworkAdapter.sendActivity(): missing serviceUrl.

I have checked the turnContext.activity values. I get : {"type":"event","name":"continueConversation"}" all other values are undefined ( serviceUrl also )

I noticed that turnContext.activityinside adapter.processActivity is not the same as in adapter.continueConversation and have all the serviceUrl and conversationId

How can I edit this code example to be able to send proactive messages to users?

The const reference needs to be ConversationReference not just the Id if you are using it for BotFrameworkAdapter.continueConversation().

A ConversationReference can be retrieved by using:

const reference = TurnContext.getConversationReference(turnContext.activity);
