Have defined all the necessary settings in the portal.

SCM_DO_BUILD_DURING_DEPLOYMENT=true
WEBSITE_NODE_DEFAULT_VERSION=12
WEBSITES_PORT=3000
WEBSITE_HTTPLOGGING_RETENTION_DAYS=7

Tried with node version 10 also but still the same error.

Answer 1

Connected with MS Support team they suggested to make the SCM_DO_BUILD_DURING_DEPLOYMENT= FALSE . After making this as false i am able to deploy the app. But the strange thing is with this option enabled i was doing earlier deployments and it was working.

Answer 2

In my case, I had the node app in a subdirectory, and this was causing this error in GitHub Actions job. Explicitly setting the working directory in the yml file fixed this. ie

- name: npm install, build, and test
    working-directory: ./subdirectory
    run: |
      npm install
      npm run build --if-present
      npm run test --if-present

Answer 3

If you're doing a deployment from ie, Visual Studio Code and deploying the dist/... folder then you wouldn't want to try and actually do a build hence setting SCM_DO_BUILD_DURING_DEPLOYMENT=false .

There is not a running node.js server to actually do a build on the agent pool deployment pipeline. Azure devops or Jenkins per se would actually have an agent pool to do a "proper (air quotes)" build. Yes, you're code is running on node hence the setting you choose when setting up the web app . So those 2 things are not the same. Rather, DevOps.

I didn't find it in the documentation so appreciate the answer and responses here; but, I just wanted to give more context to the answer.

It's an upgrade to visual studio web apps deployment to potentially utilize other build methods like described in an answer here about github actions.

Answer 4

I also struggled with this issue.

Two things helped me:

When deploying from the Azure App service extension:

1. Understanding that your root NodeJS application folder must be the root folder that is open in your explorer in vscode.

If your NodeJS application is in a subfolder, azure wont be able to build ( or identify your node platform: hence the error message that you are seeing ) the scripts in your root folder.

By far the easiest way to resolve this is to open vscode in the root folder ( the folder where your package.json file is located.

• Also: When you click the deploy button on your vscode Azure App service extension: it might allow you to specify the folder to be deployed.

2. You can try to add the Application setting: SCM_DO_BUILD_DURING_DEPLOYMENT with the value of FALSE and Deployment slot setting of unchecked.

This is on the azure portal under configuration - application settings - add +

Remember to click that save button after adding new application settings..... because azure... lol.

But i think this is mostly way to delay your app building until the files are copied.

Last thing: If you are deploying from Github: Make sure that your nodeJS app is also in the root folder of the Github repo. If it is not you will need to update the workflow file to change the folder to the subfolder.

You just need to add cd yourfoldername above the line where it says npm install and commit the workflow change to the repo.

Hope this helps.
