FastAPI Item Creation with Exception Handling

This function creates an item using FastAPI and Pydantic, handling exceptions that may occur during the item creation process. It accepts a Pydantic model containing item information and returns the created item. If an exception occurs during item creation, it raises an HTTP exception.
