If you’re using Azure functions under Node.j2 20 runtime version, you need to upgrade it at least to Node.js runtime version 22. This is because support, including security patches, will won’t be available after 4/30/2026.
Warning message: Upgrade your app to newer version as Node.js 20 LTS has reached EOL on 4/30/2026 and is no longer supported.
