These are the settings on my web appUser's image

However my deployments were never successful. Then I find this on the websites' bash:
User's image

How is that the case? And how do I fix this? I never specified v18 in any of my work on this webapp, not once.

    Check your package.json or local node version. It may be referring to an older version of node. You'll notice I created a web app using Node 20 but was changed to match the runtime version on my local machine. To fix, make sure your local environment and package.json is using Node 20.

    appsvclinux ssh host

    vscode terminal


    EDIT 2023 Dec 6 Based off your I'm updating my answer. I have verified the following steps do indeed work.

    1. Set the runtime in either the portal or run az webapp config set --name <app name> --resource-group <resource group> --linux-fx-version "NODE|20-lts". If using PowerShell, use --% to escape the | in --linux-fx-version argument.
    2. Restart the app service either via portal or az webapp restart --name <app name> --resource-group <resource group>

    When you start a new SSH session, you should see the NodeJS version updated upon the start of the session.
