Unsupported Node.js version! Your version: undefined

To Reproduce

git checkout https://github.com/richtera/wownar
cd wownar
yarn
yarn build

The same thing happens with yarn pages:build which is why I posted an issue there first https://github.com/cloudflare/next-on-pages/issues/791

Current vs. Expected behavior

Currently is errors out because the polyfill for process doesn't have version on it. Rewriting the polyfill as

function createProcessPolyfill() {
    const processPolyfill = {
        env: buildEnvironmentVariablesFrom(),
        version: process.version
    };
    const overridenValue = {};
    for (const key of Object.keys(process)){
        if (key === "env" || key === "version") continue;
        Object.defineProperty(processPolyfill, key, {
            get () {
                if (overridenValue[key] !== undefined) {
                    return overridenValue[key];
                }
                if (typeof process[key] === "function") {
                    return ()=>throwUnsupportedAPIError(`process.${key}`);
                }
                return undefined;
            },
            set (value) {
                overridenValue[key] = value;
            },
            enumerable: false
        });
    }
    return processPolyfill;
}

makes builds pass. I can't tell when this started or anything about that however. This is just a fresh nextjs project I got from elsewhere https://github.com/neynarxyz/farcaster-examples/tree/main/wownar and the bug is inside of next.js

Additional context

Since the code in canary is still missing "version" I am not sure if makes sense to attempt a canary build.

Once you modify the polyfill it gets further but I have problems with my /404 routing so I will push a fix for that.

[richtera]

Added a branch "patched" into my repo which patches nextjs and fixes the routing issues to deploy the whole thing on cloudflare to make sure all the pieces work together.

hey @richtera - have you had any luck with the next team on this? facing a similar issue

[richtera]

No they didn't agree it was their issue. You're welcome to use my patch. Maybe if you ping them separately?
