订阅循环中的异常:未配置订阅密钥

Exception in subscribe loop: Subscribe key not configured

有人可以帮我弄清楚为什么我会收到此异常吗?虽然我配置了订阅键,但好像没有。

这里是异常:“订阅循环中的异常:未配置订阅密钥 重新连接策略已禁用,请手动处理重新连接。"

我无法收到错误“订阅循环异常:订阅密钥未配置重新连接策略已禁用,请手动处理重新连接。”。

我使用了代码块:

pnconfig = PNConfiguration()
pnconfig.subscribe_key = "my_subkey"
pnconfig.publish_key = "my_pubkey"
pnconfig.ssl = True
pnconfig.uuid = "my_custom_uuid"
pnconfig.reconnect_policy = "LINEAR"
pubnub = PubNub(pnconfig)

来自页面:https://www.pubnub.com/docs/python/api-reference-configuration 并添加:

PNReconnectionPolicy.NONE
