.venv\lib\site-packages\allure_commons\lifecycle.py:137: KeyError

Comienza reproduciendo el fixture con ámbito de sesión en test/conftest.py e inspecciona test/commons/utils/reporting_utils.py, especialmente attach_json_to_report. Sigue el fallo reportado a través del ciclo de vida de allure_pytest_bdd y allure_commons lifecycle.py. Se considera terminado cuando los adjuntos de los fixtures previos a la prueba ya no provocan un KeyError cuando no hay ningún elemento ejecutable activo.
