We are keeping your runtime up to date with industry standards. In accordance with OpenJS Foundation’s support schedule, Node v10 will no longer be supported after April 30, 2021. A new deployment will be required to make Functions run against the new Node version.
Your currently deployed functions will continue to execute on the existing Node v10 runtime if no changes are made. If you deploy functions after April 30, they will automatically deploy to Node v12.
Follow theseinstructions to upgrade, test and deploy your code and ensure a safe transition to Node12.
We recommend that you upgrade to NodeJS 12 even if you’re not planning on making other changes. Test and re-deploy your code with Node12. After April 30th, 2021, if you make changes to your Functions, they will deploy to NodeJS 12.
Currently, the Node version will only change if you explicitly set the Node version via either the UI dropdown in the dependencies tab, by passing runtime using serverless toolkit or by explicitly setting the runtime parameter when creating a Build.
