> Have to add safe navigation operator here due to return of `nil` when exception occurs (which we rescue and track in `run_pipeline_step`). I had another idea of returning 'empty `ExtractedData` response object' when this happens but since we rescue in `run_pipeline_step` which is used in transformation and loading, we can't return empty `ExtractedData` object there.
