I want to make a chat room. I follow the step with MS tutorial.
My folder is like figure1.

But the function doesn’t be create. When I go to azure portal, I saw the Function app is created successfully, but their is no any function can be trig (fig2).

I use function start locally and it works fine, but I put it in azure and it doesn’t work.

here is my message.js code (I apologize for not being able to reveal the contents of the function getAIResponse, but I don’t think this program affects the deploy function.)

const { WebPubSubServiceClient } = require('@azure/web-pubsub');
const { app: azureApp } = require('@azure/functions');
const { OpenAIClient, AzureKeyCredential } = require("@azure/openai");

const connectionString = process.env["AzureWebPubSubConnectionString"];
const hubName = 'simplechat';
const serviceClient = new WebPubSubServiceClient(connectionString, hubName);

// Azure Function (PubSub WebSocket)
azureApp.http('message', {
    methods: ['POST', 'OPTIONS'],
    authLevel: 'anonymous',
    handler: async (request, context) => {
        if (request.method === 'OPTIONS') {
            return {
                status: 204,
                headers: {
                    'Access-Control-Allow-Origin': '*',
                    'Access-Control-Allow-Methods': 'POST, OPTIONS',
                    'Access-Control-Allow-Headers': 'Content-Type, Authorization',
                    'Access-Control-Allow-Headers': 'X-Requested-With, content-type',
                    'Content-Type': 'application/json'
                }
            };
        }

        try {
            const body = await request.json();
            const message = body.messages;
            if (!message) {
                return {
                    status: 400,
                    headers: {
                        'Access-Control-Allow-Origin': '*',
                        'Content-Type': 'application/json'
                    },
                    body: JSON.stringify({ error: "Message is required", data: request })
                };
            }




            const aiResponse = await getAIResponse(body);
            await serviceClient.sendToAll(aiResponse, { contentType: "text/plain" });

            return {
                status: 200,
                headers: {
                    'Access-Control-Allow-Origin': '*',
                    'Content-Type': 'application/json'
                },
                body: JSON.stringify(aiResponse)
            };
        } catch (error) {
            return {
                status: 500,
                headers: {
                    'Access-Control-Allow-Origin': '*',
                    'Content-Type': 'application/json'
                },
                body: JSON.stringify({ error: error.message })
            };
        }
    }
});
