Warning when pushing to GitHub for Azure Node.js Web App: "Node.js 12 actions are deprecated"

I have recently created a Node.js Web App in Azure.

(This question relates to the Azure environment specifically and is therefore not a duplicate of this question: Github actions for Rust shows Node.js warning (12 - 16). Additionally, that question does not contain a solution to my question).

I associated a GitHub repo with the application when I was prompted to.

This automatically created a folder structure in my repo like this:

.github > workflows > main_myAppName.yml

I assumed that was the 'workflow' which pushes the code to Azure after a git push.

I changed some files in my local repo, added, committed and pushed to GitHub.

I could see the workflow running in GitHub at this URL:

https://github.com/username/repo_name/actions/runs/0123456789

The page displayed this warning:

build
Node.js 12 actions are deprecated. For more information see: https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/. Please update the following actions to use Node.js 16: actions/checkout@v2, actions/setup-node@v1, actions/upload-artifact@v2

Because I did not create this 'workflow' file, or have any idea how to use it, I don't know how to resolve this warning.

Question:

• Should Azure be automatically changing the workflow file so that it is in accordance with GitHub's requirements?

• Or will I need to monitor changing requirements for 'workflow' files in the future and learn how to apply the required fixes?

To clarify, I am nervous about changing the 'workflow' file because I am not familiar with it and don't want to mess anything up. I was hoping that Azure would just take care of making the required updates to that file.

Below is a screenshot of the warning messages on the build/deployment/actions page.

(For reference, I am using the Free web app tier in order to test the functionality of Azure. I am assuming this is why the build and deployment took over 30 minutes. I also don't know why I am getting a warning about over 10,000 files in this artifact - there are definitely not 10,000 files in my app, and node_modules is, ofcourse, specified in the .gitignore file).

Edit:

Below is the contents of the workflow file at GitHub named:

https://github.com/username/repo_name/blob/main/.github/workflows/main_myAppNameHere.yml

If it is my responsibility to update this file, can anyone please provide guidance on exactly what needs to be changed in it - the workflow file is a completely new concept for me, so I don't understand it.
