[Bug] Deployment Fails: "Application error: a client-side exception has occurred" when using @splinetool/react-spline in Next.js

[NurNils]

When deploying a Next.js 15+ project to Vercel with @splinetool/react-spline, the deployed site fails to load and shows the error:

"Application error: a client-side exception has occurred while loading the app."

🔁 Steps to Reproduce

1. Use Next.js 15
2. Install @splinetool/react-spline
3. Add the following component:

'use client';
import dynamic from 'next/dynamic';

const Spline = dynamic(() => import('@splinetool/react-spline'), { ssr: false });

export default function Example() {
  return (
    <Spline scene="https://prod.spline.design/xxxxx/scene.splinecode" />
  );
}

I solved the problem by adding this in my nextjs config

webpack: (config, { isServer }) => {
	if (!isServer) {
		config.optimization.innerGraph = false;
	}
	return config;
},

Please give me a code example. For me it's still not working.
