Three possibilities:

1. The IDE inputs (e.g. arguments and environment variables) are not the same as the command line inputs. You can check that with print statements or logging.
2. The libraries are not the same. I assume you know how to check this.
3. You found a timing problem. To check this, first determine which element is erroring out, then try waiting before accessing that element.
