ModuleNotFoundError: Cannot find module next/dist/compiled/lib/ModuleNotFoundError when using Next.js 15

[sahul-e]

Hi team 👋,

I'm trying to use @module-federation/nextjs-mf with Next.js v15.3.2, and I'm running into an issue when starting the dev server:

Error: Cannot find module 'next/dist/compiled/lib/ModuleNotFoundError'
Require stack:
- node_modules/@module-federation/nextjs-mf/node_modules/@module-federation/enhanced/dist/src/lib/sharing/resolveMatchedConfigs.js
...

It looks like the plugin is relying on a private/internal Next.js file that may have been removed or moved in Next 15.

❓ Request for Help
I’m not in a position to downgrade Next.js, so I'm hoping to continue using nextjs-mf with the latest Next version.

Could someone from the team guide me on:

• Whether this is something actively being worked on?
• A potential workaround or patch I could apply in the meantime?
• Whether there's a plan to support Next.js 15 officially?

I’d be happy to test or contribute a fix if there’s a direction to go in. 🙏

📦 Versions

• next: 15.3.2
• @module-federation/nextjs-mf: 8.8.26
• Node: 22
• OS: macOS

✅ Repro Steps

1. Create a Next.js 15 project
2. Add @module-federation/nextjs-mf
3. Add NextFederationPlugin to next.config.js (const NextFederationPlugin = require('@module-
   federation/nextjs-mf') )
4. Run npm run dev

🔎 Root Cause

The plugin relies on the internal file next/dist/compiled/lib/ModuleNotFoundError which was removed in Next.js 15.

Same issue, did you find a fix for your problem?

[sahul-e]

So far, I haven’t found any solution to this issue.

[GeorgeVictor8]

@sahul-e the only solution i have found so far was not using NextFederationPlugin and using Vanilla ModuleFederationPlugin whilst this is bad because its not going to render SSR in a next.js project but you still utilize most of the capabilities of Module-Federation
but still i believe its not a solution its just a work-around

@sahul-e any update?

[GeorgeVictor8]

@sahul-e hey, good news i have solved the issue
i have got a compatible version for next.js with webpack and the module-federation/next-mf and these are the versions that are compatible with each other that hence solves the issue
let me explain what i have done

try downgrading to this next version

    "next": "^14.0.3",
    "webpack": "5.96.1",
     "@module-federation/nextjs-mf": "8.7.8",
    "@module-federation/runtime": "0.7.3",
    

and also in your build script and start-dev or dev you need to add this key to let know next js to use the local webpack instead of the its own webpack version
for example

"dev": "rm -rf .next; NEXT_PRIVATE_LOCAL_WEBPACK=true
following these steps i have been able to make the NextFederationPlugin work

@GeorgeVictor8
Sorry for the late reply — I was actually trying to make this work with next 15, since I can't downgrade in my current setup. That said, your solution with next 14 is super helpful — really appreciate you sharing the compatible versions and the workaround with NEXT_PRIVATE_LOCAL_WEBPACK=true. Great job figuring that out!

@sahul-e have you tried using Next15 + Rspack to see if the error is the same?
