KedroContextError in empty 'kedro new' project: expected `ConfigLoader` is `NoneType`

Description

My fairly new project runs into kedro.framework.context.context.KedroContextError: Expected an istance of "ConfigLoader", got "NoneType" instead. I tried to follow the error, and I believe that the Hooks are not loaded yet, however the logger is already trying to use them.

Since I am trying it on my Work station where I don’t have access to github ( I know, kill me pls) I am typing this out and can’t really copy paste long error messages. Sorry.

I proceded to try it with a completely empty project (kedro new, kedro ipython) which runs into the same issue.

Context

In my new Project I have followed the two tutorials https://kedro.readthedocs.io/en/latest/03_tutorial/04_create_pipelines.html https://kedro.readthedocs.io/en/latest/11_tools_integration/01_pyspark.html

only after which I tried ‘kedro run’, which lead to the Issue.

Steps to Reproduce

1. kedro --version -> 0.17.1
2. kedro new
3. kedro ipython

Expected Result

the session should be able to start.

Actual Result

As I said, no copy paste 😦

with KedroSession.create(....
...
conf_logging = self.get_logging_config()
...
return self._get_config_loader().

the Exception raised is in this function where I added one line of debug:

    def _get_config_loader(self) -> ConfigLoader:
        """A hook for changing the creation of a ConfigLoader instance.
        Returns:
            Instance of `ConfigLoader` created by `register_config_loader` hook.
        Raises:
            KedroContextError: Incorrect ``ConfigLoader`` registered for the project.
        """
        conf_root = settings.CONF_ROOT
        conf_paths = [
            str(self.project_path / conf_root / "base"),
            str(self.project_path / conf_root / self.env),
        ]
        hook_manager = get_hook_manager()
        config_loader = hook_manager.hook.register_config_loader(  # pylint: disable=no-member
            conf_paths=conf_paths, env=self.env, extra_params=self._extra_params,
        )

        # I ADDED THIS:
        print(hook_manager.hook.register_config_loader.get_hookimpls()) --- > []
    
        if not isinstance(config_loader, ConfigLoader):
            raise KedroContextError(
                f"Expected an instance of `ConfigLoader`, "
                f"got `{type(config_loader).__name__}` instead."
            )
        return config_loader

This is why I believe that the hooks are not registered yet.

I added configure_project(Path(__file__).parent.name) to my main function and works now.

Thanks for your help @MerelTheisenQB!

Hi @Spooky-0 , this is a known issue which we will very soon release a fix for. In the meantime we recommend to just roll back to Kedro 0.17.0.
