langflow应用卡在思考阶段没有响应

Question

我已成功安装langflow（0.4.0）。我测试了第一个应用程序“带有提示和历史记录的基本聊天”。在 ChatOpenAI 面板输入 openai_key 并将“输入键”设置为“文本”后，我成功构建了应用程序。然而，当我打开聊天界面并问一个问题“你好”时，应用程序陷入了如下所示的思考：

我也测试过其他应用程序，也有同样的问题。

langflow 安装在服务器上。我确信服务器可以连接到互联网。

reddit 上有一个类似的问题：langflow：聊天没有响应

问题出在 Open AI API 上。仅仅注册帐户或创建 API 密钥还不够。您必须设置计费。否则，您的 API 将仅连接但不会响应。 platform.openai.com > 设置 > 账单

一旦我完成所有设置，我的聊天就能够生成响应。
