javascript - 在 Node.js 中使用带有 GRPC 的 Google Assistant SDK 时“解析服务器响应失败”

Question

我已经创建了一个双向流assistant.converse()，并且发送音频成功。

const assistant = new protocol.EmbeddedAssistant(ASSISTANT_API_ENDPOINT, credentials);
const conversation = assistant.converse();
conversation.on('data', data => {
  console.log(data);
});

conversation.on('error', err => {
  console.log(err);
  micStream.end();
});
conversation.write({ config }); // audio type config
micStream // an object that provides an audio stream
  .pipe(through2.obj((chunk, enc, cb) => cb(null, { 'audio_in': chunk })))
  .pipe(conversation);

当我停止说话并且助手检测到静音时，助手会抛出此错误：
