I’m trying to run an app using nextJS with fuels. When it compiles it gives the following error

SyntaxError: Named export ‘ec’ not found. The requested module ‘elliptic’ is a CommonJS module, which may not support all module.exports as named exports.

I can fix this locally by changing the import on

to  
import pkg from"elliptic";

const p = pkg.ec

But this fix is not valid when building the project on vercel. Is there a workaround for this ?

Great question! You need to change the next config to set esmExternals to false.

```auto
experimental: {
    esmExternals: false,
 },

```

You can see an example here: [webgum/next.config.js at main · Webgum/webgum · GitHub](https://github.com/Webgum/webgum/blob/main/next.config.js)
