Node.js has a published release schedule. Update your function apps to Node.js 14 to ensure you’re on the latest long term supported version.
When you run Azure Functions locally, it uses the default version of Node.js on your machine. Download and install Node.js 14. While Node.js is highly compatible with earlier versions, make sure to test your app locally and in Azure. To change a function app’s Node.js version in Azure, see the Azure Functions Node.js Developer Guide.
