ERROR: Module did not self-register

[ghost]

Application run for a while but then crashes on said error. In my case: Error: Module did not self-register: '/home/vojtech/Work/myproject/node_modules/isolated-vm/out/isolated_vm.node'.

Isolated-vm runs in separated thread-worker. After every evaluation i release context, jail and script and before another one i create new ones.

OS: Ubuntu 22.04.3 LTS
NODE: v16.20.2
build-essential: 12.9ubuntu3
g++: 4:11.2.0-1ubuntu1
python: Python 3.10.12
gcc 11.4.0

Whole stack trace looks like this:

node:internal/event_target:1011
  process.nextTick(() => { throw err; });
                           ^

What i have tried: Rebuild with npm rebuild, reinstall package, tried node 18 and behavior did not change.

Any ideas what am i missing or how to fix this?

Are you using workers? If so can you try importing isolated-vm from the primary module? You don't have to do anything with it, just import to create a strong reference. This is probably #402.

It looks like creating strong reference in main thread did the trick. Thank you.
