Running into "ReferenceError: P is not defined" in build process

[SebastianPfeu]

In my next js app, as soon as I run npm run build, I get the error "ReferenceError: P is not defined" (therefore I cannot deploy). I found out that the issue is in the <ShaderGradient> component. However, no matter what changes I make, the error persists. Running the project locally works perfectly fine. Is this error known? How can I solve it?

The relevant code snippet is the following (quite similar to the code provided in the README file):

"use client"

import { ShaderGradientCanvas, ShaderGradient } from '@shadergradient/react'
import * as reactSpring from '@react-spring/three'

export default function GradientBackground() {
  return (
    <ShaderGradientCanvas
      style={{
        position: 'absolute',
        top: 0,
      }}
    >
      <ShaderGradient
        control='query'
        urlString='https://www.shadergradient.co/customize?animate=on&axesHelper=off&bgColor1=%23000000&bgColor2=%23000000&brightness=1.2&cAzimuthAngle=180&cDistance=3.6&cPolarAngle=90&cameraZoom=1&color1=%2352ff89&color2=%23dbba95&color3=%23d0bce1&embedMode=off&envPreset=city&fov=45&gizmoHelper=hide&grain=on&lightType=3d&pixelDensity=1&positionX=-1.4&positionY=0&positionZ=0&reflection=0.1&rotationX=0&rotationY=10&rotationZ=0&shader=defaults&type=plane&uDensity=1.3&uFrequency=5.5&uSpeed=0.4&uStrength=4&uTime=0&wireframe=false&zoomOut=false'
      />
    </ShaderGradientCanvas>
  )
}

My package.json file looks as follows:

"dependencies": {
    "@react-spring/three": "^9.7.5",
    "@react-three/drei": "^9.120.5",
    "@react-three/fiber": "^8.17.10",
    "@shadergradient/react": "^2.0.19",
    "next": "14.0.3",
    "react": "^18",
    "react-dom": "^18",
    "three": "^0.169.0"
  },
  "devDependencies": {
    "@types/node": "^20",
    "@types/react": "^18",
    "@types/react-dom": "^18",
    "@types/three": "^0.169.0",
    "autoprefixer": "^10.0.1",
    "eslint": "^8",
    "eslint-config-next": "14.0.3",
    "postcss": "^8",
    "tailwindcss": "^3.3.0",
    "typescript": "^5"
  }

Edit 1: Problem persists even with lower versions of three (v0.150.0 and v0.154.0)
Edit 2: Build process succeeds when using plain react (e.g. via vite) instead of next js
