  This is most likely because your project has a code error.
  Check your project logs, fix the error and try again.


:confused:

Worker threads are only supported in node 10.5.0+ - can you check what version of node you’re using by running node --version in the terminal?
If your node version is between 10.5.0 and 11.7.0, simply add --experimental-worker to your start script.
Otherwise, in your package.json you should add an engines propert which is an object, with node as the version of node you’d like - I’d recommend going for 14.x as that’s the most recent that glitch supports. Example:

"engines": {
  "node": "14.x"
}

@RiversideRocks, worker_threads is a built-in package in node, like fs or path :slight_smile:
