How do we deploy azure function in VS Code?

I followed the deployment guide precisely here https://learn.microsoft.com/en-us/azure/azure-functions/functions-develop-vs-code?tabs=nodejs#republish-project-files

However, After deploying, In Azure portal, there is no functions in function app.

And in the output log in VS code:

I have completely no clue now.
What should I do?

I followed the given MS DOC and I can able to deploy my function to funtion app.

My function runs successfully locally as below,

In order to use Azure Function Core tools command to deploy the Function like below:-

Open your Vs Code terminal and run the commands below:-

az login
az account set --subscription "subsription-name"
func azure functionapp publish functionapp-name

The function got deployed successfully to the function app at Azure Portal as below,

The code runs successfully at Azure Portal also as below,

Coming to your error code, Some times, there might be corruption in the node_modules directory. To fix this, delete the “node_modules” folder and reinstall all dependencies.

You can try the below command to install node_modules,

npm install rimraf --save-dev

Below is my package.json file,

package.json:

{
  "name": "your-project-name",
  "version": "1.0.0",
  "description": "",
  "scripts": {
    "start": "func start",
    "test": "echo \"No tests yet...\"",
    "clean": "rimraf dist"
  },
  "devDependencies": {
    "rimraf": "^5.0.1"
  }
}

Run the below commands and try again,

npm install

Then try to run your code with fn+f5 and deploy that to function app.

Looks like I failed to build before deploying:

I need to run this first:

npm run-scripts build

Then a dist folder will be generated after the build.

Then I can do the deploying steps, and the function would appear.
