## Handling Array Query Parameters

For query parameters expected to be arrays, use the utility functions from `@query-array-preprocessor.ts`:

- **`createQueryArrayPreprocessor`**: Converts required string query parameters into arrays.
- **`createOptionalQueryArrayPreprocessor`**: Converts optional string query parameters into arrays, allowing them to be undefined.

These functions ensure proper handling of array inputs, even when provided as single or comma-separated strings.
