Module did not self-register

[CumpsD]

I am trying out blake3 2.1.7 but am getting the following error:

node:events:346
      throw er; // Unhandled 'error' event
      ^
Error: Module did not self-register: '/home/ubuntu/ironfish-src2/node_modules/blake3/dist/native.node'.

I have tried using Node 16 with ubuntu-latest-93.node and Node 15 with ubuntu-latest-88.node but both give the same error.

Any ideas what causes this error?

I'm facing this issue as well. I've figured out that it occurs when I have instances of require('blake3') in both the main thread and worker thread at the same time.

index.js

const {Worker} = require("worker_threads");

const blake3 = require('blake3');

const worker = new Worker("./worker.js");

worker.once("message", result => {
  console.log(result);
});

worker.on("error", error => {
  console.log(error);
});

worker.on("exit", exitCode => {
  console.log(exitCode);
})

worker.js

const blake3 = require('blake3');

const {parentPort, workerData} = require("worker_threads");

parentPort.postMessage(doNothing())

function doNothing() {
  return null;
}

Edit: It also occurs when running multiple instances of the workers at the same time. It seems to be a general issue of multiple threads using the native binding. The workaround looks to be to userequire('blake3-wasm') instead and skipping the native binding.
