MS Teams Bot - End Of Conversation Activity Not Working

Occasional Visitor

I am trying to implement master and skill bot in which Master Bot routes the request to specific Skill bot. After request reaches the skill bot , all incoming requests are handled by skill bot until it sends

EndOfConversation Activity Type. When Master Bot identifies this activity  type , it ends the conversation and then user can converse with master bot.  For this i am using node js Skill. This code works fine in Bot Emulator but it gives error on MS Teams Bot. 
class EchoBot extends TeamsActivityHandler{
    constructor() {
        this.onMessage(async (context, next) => {
            switch (context.activity.text.toLowerCase()) {
            case 'end':
            case 'stop':
                await context.sendActivity({
                    type: ActivityTypes.EndOfConversation,
                    code: EndOfConversationCodes.CompletedSuccessfully
                await context.sendActivity(`Echo (JS) : '${ context.activity.text }'`);
                await context.sendActivity('Say "end" or "stop" and I\'ll end the conversation and back to the parent.');

            // By calling next() you ensure that the next BotHandler is run.
            await next();
[onTurnError] unhandled error: Error: Unknown activity type
