Decorator for using dicts/lists with python LRU Cache

Python LRU Cache with non hashable inputs

def hashable_lru(func):
    cache = lru_cache(maxsize=1024)

    def deserialise(value):
        try:
            return json.loads(value)
        except Exception:
            return value

    def func_with_serialized_params(*args, **kwargs):
        _args = tuple([deserialise(arg) for arg in args])
        _kwargs = {k: deserialise(v) for k, v in kwargs.items()}
        return func(*_args, **_kwargs)

    cached_function = cache(func_with_serialized_params)

    @wraps(func)
    def lru_decorator(*args, **kwargs):
        _args = tuple([json.dumps(arg, sort_keys=True) if type(arg) in (list, dict) else arg for arg in args])
        _kwargs = {k: json.dumps(v, sort_keys=True) if type(v) in (list, dict) else v for k, v in kwargs.items()}
        return cached_function(*_args, **_kwargs)
    lru_decorator.cache_info = cached_function.cache_info
    lru_decorator.cache_clear = cached_function.cache_clear
    return lru_decorator

Inspired by your idea, I created a more generic version:
