    func start is stuck, neither shows any error nor listen to 7071 port. so weired.I am using nodejs

    Can you check your Node.js application code to ensure that the server is being created properly and that it’s listening on the correct port. otherwise function should run on specific port like func start --port 7072 command.

    Run this npm install -g azure-functions-core-tools@latest command for latest version of azure function core tools.

    Ensure that all dependencies required by your application are installed correctly. Run npm install to install any missing dependencies or update existing ones.

    I have created Http trigger function with runtime stack Node.js in visual studio code by using func init and func newcommands.

    function code:

    const { app } = require('@azure/functions');

app.http('httpTrigger', {
    methods: ['GET', 'POST'],
    authLevel: 'anonymous',
    handler: async (request, context) => {
        context.log(`Http function processed request for url "${request.url}"`);

        const name = request.query.get('name') || await request.text() || 'world';

        return { body: `Hello, ${name}!` };
    }
});

    host.json:

    {
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  },
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[4.*, 5.0.0)"
  }
}

    The function executed successfully. check below:

    check below steps to deploy the function into azure portal.

    after selecting the folder and subscription plan and function app should clicked on deploy button like below:

    In some use cases, this might happen if the function app is trying to connect to a storage account but cannot do this.
    To solve this, you have 2 options:

    1. Use Azurite to simulate local storage. If you’re using VS Code, the extension works really great!
    2. Connect to an actual storage account that is hosted on Azure. To do that, just set the connection string in the local.settings.json file with the key AzureWebJobsStorage.
