Hi fellows, I am trying to update an old

kedro

code from

0.18.12

to

1.0.0

step by step, starting with version

0.19.15

. We had set up a test to be sure that our custom resolvers were working that reads as

def test_custom_resolvers_in_example(
    project_path: Path,
) -> None:
    bootstrap_project(project_path=project_path)

    # Default value
    with KedroSession.create(
        project_path=project_path,
        env="example",
    ) as session:
        context = session.load_context()
        catalog = context._get_catalog()
        assert timedelta(days=1) == catalog.load("params:example-duration")
        assert datetime(1970, 1, 1, tzinfo=timezone.utc) == catalog.load(
            "params:example-epoch"
        )

It turns out this test was passing with version

0.18.12

with

CONFIG_LOADER_CLASS = OmegaConfigLoader

but it fails in version

0.19.15

. It seems that the environment is not taken into account and that the loader parses all the possible environments (therefore finding duplicates).

E           ValueError: Duplicate keys found in .../conf/local/catalog.yml and .../conf/production/catalog.yml: hourly_forecasts, output_hourly_forecasts

Duplicate keys

doesn't seem to bring any message on Slack. Please let me know the mistake I made. Thanks in advance!
