A worker process has failed to exit gracefully 

Hi Yoni, when running `npm run test` with node 18.1.0, tests are passing, but I'm getting this error message: 
```
A worker process has failed to exit gracefully and has been force exited. This is likely caused by tests leaking due to improper teardown. Try running with --detectOpenHandles to find leaks. Active timers can also cause this, ensure that .unref() was called on them.
```
