which is probably why it does not work for me, right?

Correct, you need to pass the entire configuration (it is stored as a blob, as opposed to the hyperparameters that are stored as individual values)
:param configuration_overrides: Optional, override Task configuration objects. Expected dictionary of configuration object name and configuration object content. Examples: {'General': dict(key='value')} {'General': 'configuration file content'} {'OmegaConf': YAML.dumps(full_hydra_dict)}
