Calling an external API from MS Teams chat bot

[lasotwamp]

Hi

I'm working on integrating MS Teams chat bot with an external API via using websockets. The problem is that after I get the response, the bot doesn't send it back to the chat. I guess the problem lies in the asynchronism of the call. Here's a code snippet:  

const { TeamsActivityHandler, CardFactory, TurnContext, TeamsInfo } = require("botbuilder");
const rawWelcomeCard = require("./adaptiveCards/welcome.json");
const rawLearnCard = require("./adaptiveCards/learn.json");
const rawModelsCard = require("./adaptiveCards/models.json");
const rawResetCard = require("./adaptiveCards/reset.json");
const cardTools = require("@microsoft/adaptivecards-tools");
const WebSocket = require("ws");

class TeamsBot extends TeamsActivityHandler {
  constructor() {
    super();
    
    this.webSocket = new WebSocket("wss://7m1s3vep8g.execute-api.us-east-1.amazonaws.com/prod");
    this.modelObj = {model: "anthropic.claude-v2"};
    this.messagesArrays = [];

    this.webSocket.onopen = async (event) => {
      console.log("connection established")
    }

    this.onMessage(async (context, next) => {
      let txt = context.activity.text;
      const removedMentionText = TurnContext.removeRecipientMention(context.activity);

      console.log("websocket - ", this.webSocket.readyState)
      
      if (removedMentionText) {
        // Remove the line break
        txt = removedMentionText.toLowerCase().replace(/\n|\r/g, "").trim();
      }
      
      // Trigger command by IM text
      switch (txt) {
        case "models": {
          const card = cardTools.AdaptiveCards.declare(rawModelsCard).render(this.modelObj);
          await context.sendActivity({ attachments: [CardFactory.adaptiveCard(card)] });
          
          break;
        }

        case "reset": {
          this.messagesArrays = [];
          const card = cardTools.AdaptiveCards.declareWithoutData(rawResetCard).render();
          await context.sendActivity({ attachments: [CardFactory.adaptiveCard(card)] });
          
          break;
        }

        default: {
          const message = {
            "role":"user", "content": txt
          };
    
          this.messagesArrays.push(message)
    
          const data = {"modelId": this.modelObj.model, "prompt": this.messagesArrays}
          const string = JSON.stringify(data);
          this.webSocket.send(string)

          this.webSocket.onmessage = async (event) => {
            const msg = event["data"]
            const trimmedMessage = msg.replace(/\n|\r|"/g, "").trim();
            const message = {
              "role":"system", "content": trimmedMessage
            };
          
            this.messagesArrays.push(message);
            console.log(this.messagesArrays)
          
            let test = await context.sendActivity("trimmedMessage");
            console.log(test)
            
            await context.sendActivity(trimmedMessage);
          }
          
          
          break;
        }
      }
      
      // By calling next() you ensure that the next BotHandler is run.
      await next();
    });

    // Listen to MembersAdded event, view https://docs.microsoft.com/en-us/microsoftteams/platform/resources/bot-v3/bots-notifications for more events
    this.onMembersAdded(async (context, next) => {
      const membersAdded = context.activity.membersAdded;
      for (let cnt = 0; cnt < membersAdded.length; cnt++) {
        if (membersAdded[cnt].id) {
          const card = cardTools.AdaptiveCards.declareWithoutData(rawWelcomeCard).render();
          await context.sendActivity({ attachments: [CardFactory.adaptiveCard(card)] });
          break;
        }
      }
      await next();
    });
  }

  // Invoked when an action is taken on an Adaptive Card. The Adaptive Card sends an event to the Bot and this
  // method handles that event.
  async onAdaptiveCardInvoke(context, invokeValue) {
    // The verb "userlike" is sent from the Adaptive Card defined in adaptiveCards/learn.json
    switch (invokeValue.action.verb) {
      case "1": {
        this.modelObj.model = "anthropic.claude-v2";
        const card = cardTools.AdaptiveCards.declare(rawModelsCard).render(this.modelObj);
       
        await context.updateActivity({
          type: "message",
          id: context.activity.replyToId,
          attachments: [CardFactory.adaptiveCard(card)],
        });
        
        break;
      }

      case "2": {
        this.modelObj.model = "Model B";
        const card = cardTools.AdaptiveCards.declare(rawModelsCard).render(this.modelObj);
       
        await context.updateActivity({
          type: "message",
          id: context.activity.replyToId,
          attachments: [CardFactory.adaptiveCard(card)],
        });

        break;
      }

      case "3": {
        this.modelObj.model = "Model C";
        const card = cardTools.AdaptiveCards.declare(rawModelsCard).render(this.modelObj);
       
        await context.updateActivity({
          type: "message",
          id: context.activity.replyToId,
          attachments: [CardFactory.adaptiveCard(card)],
        });

        break;
      }
    }

    return { statusCode: 200 };
  }
