nats jetstream在调用stream_info（stream_name）时正在计时。

Question

引起错误 nats.errors.timeouterror：nats：超时

if self.nc.is_connected:
            log.info(f"NATS client successfully connected to {SERVERS}")
            # Create jetstream context and check if stream exists
            self.nc = self.nc.jetstream()
            log.info("Created contextual JetStream object!")
            try:
                # Check if the JetStream exists [Client has already created JetStream and subject associations]
                acc_info = await self.nc.account_info()
                info = await self.nc.stream_info(STREAM_NAME)

在添加流之前使用jetstream上下文时，代码正在错误。删除流并在拨打stream_info（）之后调用notFoundError后，返回并处理。为什么返回的异常突然改变？任何帮助将不胜感激。

File "/usr/local/lib/python3.9/site-packages/nats/js/manager.py", line 65, in stream_info
    resp = await self._api_request(
  File "/usr/local/lib/python3.9/site-packages/nats/js/manager.py", line 158, in _api_request
    msg = await self._nc.request(req_subject, req, timeout=timeout)
  File "/usr/local/lib/python3.9/site-packages/nats/aio/client.py", line 899, in request
    msg = await self._request_new_style(
  File "/usr/local/lib/python3.9/site-packages/nats/aio/client.py", line 939, in _request_new_style
    raise errors.TimeoutError
nats.errors.TimeoutError: nats: timeout

• 是您的nats-server配置为启用JetStream功能（即在其配置文件中或传递-JS命令行参数）？

• 您的帐户是否允许使用Jetstream？ NATS帐户信息将告诉您。
