我正在处理文本转录的服务器端语音，我能够使一个端点端点用于较小的文件，但是任何大于〜7MB的东西都会引发错误的错误对我来说很有意义。
我知道此代码适用于小文件，并且回调URL已正确注册。我尝试在settimeout((函数中抛出" readableTranscriptStream"创建，只是为了确保这不是未传递给CreateJob调用的完整文件的问题。我还尝试过将req.file.buffer作为音频参数的参数。我也知道这不是编码文件不正确的问题，因为我使用了同一音频文件，慢慢增加了文件的长度和大小，直到丢弃此错误，直到我碰到我7.2MB，或在16位编码文件中的音频〜3分钟。
我也尝试使用fs.CreateFileStream('./local_test.wav'(作为一个参数并回到了相同的错误，尽管当我尝试过时，错误中的_requestbodylength字段是10485760，而e则是10485760，而是_requestBodyBuffers是一系列对象。我意识到这10485760与MaxBodyLength相同，但是API的文档说："您最多可以通过请求传递1 GB，最小值100字节的音频"，测试音频再次〜7.2MB。

在实例化secemttotext
时尝试添加maxContentLength: Infinity作为选项 const speechToText = new SpeechToTextV1({
username: 'user',
password: 'pass',
version: '2019-01-01',
maxContentLength: Infinity,
});
