Due to the version mismatch, we could not deploy the application with cloudflare. I have made a project on MacOS, uploaded(pushed) to git, and tried to build&deploy on CloudFlare without any environment setting changes. build code : npx @cloudflare/next-on-pages@1 (default value)

Looks like build image on cloudflare (runtime v2) is using Node.js 18.17.1, this might be needed to be upgraded?

For node version config options, see https://developers.cloudflare.com/pages/configuration/build-image/#languages-and-runtime
