util_1.promisify is not a function

[RashmiBK5]

I am trying to deploy .net core Web Api (.net 6) to Azure web app but I am getting an error
"C:\PROGRA2\SITEEX1\NODEAP1\2101.4\nodejs\node_modules\applicationinsights\out\Library\FileSystemHelper.js:43
exports.statAsync = util_1.promisify(fs.stat);"

the same workflow was working fine till last working day, but all of a sudden it is throwing exception

Log from last working day:
Generate deployment script was success full with script:

Using cached version of deployment script (command: 'azure -y --no-dot-deployment -r "C:\local\Temp\zipdeploy\extracted" -o "C:\home\site\deployments\tools" --basic --sitePath "C:\local\Temp\zipdeploy\extracted"').

But now getting an error related to Node.js.

Yaml File:

- name: Download artifact from build job
  uses: actions/download-artifact@v3
  with:
    name: webapp

 - name: Deploy to Azure WebApp
  uses: azure/webapps-deploy@v2
  with:
    app-name: ${{ env.AZURE_WEBAPP_NAME }}
    publish-profile: ${{ secrets.FredApiAppService_0F0E }}
    package: '.'

Error:

I'm getting exactly the same error trying to deploy several webapps.

Hi @AndyEdmonds
I added WEBSITE_NODE_DEFAULT_VERSION =14.17.0 in Web app environment setting and it started working.

Hi Rashmi, Thanks, will try it.

Hi @RashmiBK5
Thank you so much for your reply. I had the same issue for several days when trying to deploy a bot from Bot Framework Composer to App Services App and Azure Bot Services. Setting the environment variable WEBSITE_NODE_DEFAULT_VERSION as 14.17.0, allow me to finally deploy the app.

For future reference, if someone else has the same issue when deploying an app from Bot Framework Composer, the following are the errors I was able to solve by following Rashmi's recommendations.
