Much love, ill take a look - however next 12 is very old and may be that characteristics in the build are different vs in newer versions like next 14

[ScriptedAlchemy]

use "@module-federation/nextjs-mf": "8.6.0" - this version seems to work.

Next12 is realy old, but we have a big app still use next12, it is a very important app to us.

[ScriptedAlchemy]

8.6.0 is last working version. I'm not sure why it stops working beyond that but you can pin there for time being

[Capricair]

@ScriptedAlchemy Thank you very much!

@ScriptedAlchemy Hello, I tried 8.6.0 and it didn't work. I want to fetch remoteEntry.js to get the component myself. I don't know what to do next, can you help me?

const url = `http://localhost:3010/_next/static/ssr/remoteEntry.js`;
const code = await axios.get(url, { responseType: "text" }).then((res) => res.data);
const script = new vm.Script(code);
const module = { exports: {} };
const context = vm.createContext({ module });
await script.runInContext(context);
await module.exports.remote.init();
const Test = await module.exports.remote.get("./test");
console.log(Test.toString());  // () => ((__webpack_require__(9798)))

[ScriptedAlchemy]

Try with the new version. We switched to esm by default now. So it may fix this

[Capricair]

@ScriptedAlchemy I tried the latest version 8.8.24 it throw error when building

@ScriptedAlchemy Hello, is there any new progress? If it's too troublesome, can you tell me how to render the component after load remoteEntry.js server side?

[ScriptedAlchemy]

downgrade till it works or upgrade next to v14. v12 is 4 years old, updating to 14 should be effortless and theres codemods to do so.
