FATAL ERROR: v8::HandleScope::CreateHandle() Cannot create a handle without a HandleScope

[mlrv]

Environment

• OS: Ubuntu 20.04
• Node version: 20.15.1 (running inside a Docker container)
• "@u4/opencv4nodejs": "7.1.2"
• opencv installed without automatic build (setting OPENCV4NODEJS_DISABLE_AUTOBUILD=1), my understanding is that opencv4nodejs detects libopencv on the container and uses that
  • dpkg -l | grep libopencv -> 4.2.0+dfsg-5

Code
The offending piece of code is very simple, quite literally creating a new Mat instance from a node buffer, i.e.

import cv from '@u4/opencv4nodejs';

async function decode(buffer: Buffer) {
    const mat = await cv.imdecodeAsync(buffer);

   // ... do something with the Mat
}

What's bizarre is that things work as intended maybe once every four times. Otherwise, as soon as I hit that code path I get the following error, which crashes the whole container.
