Looking at the failing test, does that test ever pass? It looks like it will always fail. This line is referencing host from stripe_connection_config, but there isn't a host in the data.

@pytest.fixture(scope="function")
def stripe_connection_config(
    db: Session, stripe_config: Dict[str, Dict], stripe_secrets: Dict[str, Any]
) -> Generator:
    fides_key = stripe_config["fides_key"]
    connection_config = ConnectionConfig.create(
        db=db,
        data={
            "key": fides_key,
            "name": fides_key,
            "connection_type": ConnectionType.saas,
            "access": AccessLevel.write,
            "secrets": stripe_secrets,
            "saas_config": stripe_config,
        },
    )
    yield connection_config
    connection_config.delete(db)
