Reviver for JSON objects.

Parameters:

  • secrets_map (dict[str, str] | None) – A map of secrets to load. If a secret is not found in the map, it will be loaded from the environment if secrets_from_env is True. Defaults to None.

  • valid_namespaces (list[str] | None) – A list of additional namespaces (modules) to allow to be deserialized. Defaults to None.

  • secrets_from_env (bool) – Whether to load secrets from the environment. Defaults to True.

  • additional_import_mappings (dict[tuple[str, ...], tuple[str, ...]] | None) – A dictionary of additional namespace mappings You can use this to override default mappings or add new mappings. Defaults to None.
