Calling API deployment returns Worker exited prematurely: signal 9 (SIGKILL) Job: XXX error

Describe the bug

Calling API deployment returns Worker exited prematurely: signal 9 (SIGKILL) Job: XXX error.

To reproduce

I'm using Docker environment on macOS via Docker Desktop for Mac. I've setup test project as per Start User guide and make a call to API deployment. API call returns this error after some time:

{
  "message": {
    "execution_status": "ERROR",
    "status_api": "/deployment/api/mock_org/b2b-invoice-process/?execution_id=caf99a46-aff6-4648-bdec-6361ca88748e",
    "error": "Worker exited prematurely: signal 9 (SIGKILL) Job: 5.",
    "result": null
  }
}

I did similar installation on two Macs, I've tried Postman and curl calls: result is the same.

Expected behavior

API should return either a processing result or error description good enough to indicate how to resolve the problem.
