What is wrong?
I get the following error when trying to use gpu.js on production (optimized code):
Uncaught Error: Unhandled declaration

On my static website built with Next.js that loads gpu.js from CDN. However, it perfectly works on local server with unoptimized code in a dev mode.
How do we replicate the issue?
- Create Next.js project.
- Add gpu.js script tag to the
_document.js: <Script src="https://unpkg.com/gpu.js@2.15.2/dist/gpu-browser.js" strategy="beforeInteractive" />
- Build the project with
next build (npm run build).
- Generate static website with
next export.
- Host the static website on a server and try to use gpu.js there.
I suppose babel does something with my kernel code, idk.
How important is this (1-5)?

I use gpu.js v2.15.2. Here is my kernel code. Seems like nothing special:
const createKernel = outputLength => new window.GPU({
mode: "gpu",
}).createKernel(
function (videoPixels, emojiPixels, emojiPixelsLength, brightness) {
let lowestDistanceIn3d = Infinity
let lowestDistanceEmojiPixelIndex = 0
for (let j = 0, i = 0; j < emojiPixelsLength; j += 3) {
const emojiPixel = [emojiPixels[j], emojiPixels[j + 1], emojiPixels[j + 2]]
const videoPixelOffset = this.thread.x * 4
const videoPixel = [
videoPixels[videoPixelOffset],
videoPixels[videoPixelOffset + 1],
videoPixels[videoPixelOffset + 2],
]
const distanceIn3d = Math.sqrt(
Math.pow(emojiPixel[0] - videoPixel[0] * brightness, 2) +
Math.pow(emojiPixel[1] - videoPixel[1] * brightness, 2) +
Math.pow(emojiPixel[2] - videoPixel[2] * brightness, 2)
)
if (lowestDistanceIn3d > distanceIn3d) {
lowestDistanceIn3d = distanceIn3d
lowestDistanceEmojiPixelIndex = i
}
i++
}
return lowestDistanceEmojiPixelIndex
},
{
output: [outputLength],
loopMaxIterations: 9999999,
}
)
