Thank you this seems to have done the trick! I added the following (plus relevant imports) to my settings.py: ``class MyTemplatedConfigLoader(TemplatedConfigLoader): def __init__( self, conf_source: str, env: str = None, runtime_params: Dict[str, Any] = None, base_env: str = "base", default_run_env: str = "local", globals_pattern: Optional[str] = None, ): super().__init__( conf_source=conf_source, env=env, runtime_params=runtime_params, base_env=base_env, default_run_env=default_run_env, globals_pattern=globals_pattern, globals_dict=runtime_params, ) CONFIG_LOADER_CLASS = MyTemplatedConfigLoader``
