Weaviate 的 client.is_ready 引发异常而不是布尔值

当我试图调用

client.is_ready()

时，出现了异常，尽管根据文档它应该返回布尔值。

我还必须提到，我正在尝试使用 Docker 启动带有自定义 Transformers 模块的 Weaviate。我试图用他们的DEMO

复制容器来导入数据

我的 Weaviate 实例需要大约一分钟才能完成启动，直到 FastAPI 在机器中显示运行地址。

我知道 Weaviate 客户端有参数

startup_period

指定等待 Weaviate 完成启动的时间，我告诉它等待 90 秒，Weaviate 实例已经启动，FastAPI 的地址已经显示在 90 秒内秒，但问题仍然存在。

下面是导入片段。它与 DEMO 仓库中的完全一样。

def main():
    client = Client("http://localhost:8088", startup_period=90)
    
    wait_time_limit = 240
    while not client.is_ready():
        if not wait_time_limit:
            sys.stderr.write("\rTIMEOUT: Weaviate not ready. \
                            Try again or check if weaviate is running.\n")
            sys.exit(1)
        sys.stdout.write(
            f"\rWait for weaviate to get ready. {wait_time_limit:02d} seconds left.")
        sys.stdout.flush()
        wait_time_limit -= 2
        time.sleep(2.0)

所以我有了Weaviate实例容器，还有导入数据的容器。当我尝试使用 Docker Compose 运行两者时，它不起作用。但是，当我让 Weaviate 完成启动并在本地用 Python 运行导入数据代码时，它就可以工作了。

但我仍然不明白为什么

client.is_ready()

不起作用，尽管我在客户端实例化中指定了

startup_period

。
