我试图围绕从您的帮助页面逐字复制的 Google Text-to-Speech 创建一个包装器。从日志看来，它似乎试图创建一个 Jetty 实例（将呼叫转发到另一个服务？）但失败了，因为它无法通过从默认值读取来为其分配网络地址。我将包括日志输出供您参考。您能否建议在使用 Cloudfunctions 时更改代码或使用不同的策略？
日志输出如下：

更新：
事实证明，导致 DEADLINE_EXCEEDED 错误的行是罪魁祸首。谷歌搜索错误表明这可能是因为客户端没有及时收到服务器的响应（在超时之前）。这是导致错误的行。
SynthesizeSpeechResponse response = textToSpeechClient.synthesizeSpeech(input, voice, audioConfig);
关于如何解决它或如何增加进程超时的任何建议？愿意试一试。
