For either(oneOf) types, we skip introspection as we cannot
determine which branch of the union was taken without more context
This *should* be safe, as it can currently mostly be triggered through
The `extraModules` setting of inventory modules.
Example:
```
importer.roles.default.extraModules = [
../../modules/nixos/common.nix
];
```
Error Message:
