      You are currently running Node.js ${nodeVersion} on this local machine. The production environment for Twilio Serverless currently supports versions ${expectedVersion}x.

      When you deploy to Twilio Serverless, you may encounter differences between local development and production.

      For a more accurate local development experience, please switch your Node.js version.
      A tool like nvm (https://github.com/creationix/nvm) can help.
