Node.js 接收：'；身份验证错误：错误：读取EconReset'；当通过代理连接到google云平台时

我一直在从事一个Node.js项目，该项目访问google cloud api。当我在外部网络中时，请求工作正常，我收到了预期的答案。但是，当我在访问smpt服务器所必需的协作代理后面时，我收到以下错误：

验证错误：错误：读取EconReset

为了通过协作代理，我使用了cntlm，并将其设置为中提到的环境代理

此外，我还启用了GRPC冗余和GRPC握手跟踪，如下面的代码所示

process.env.GRPC_VERBOSITY = 'DEBUG'
process.env.GRPC_TRACE = 'handshaker'

process.env.HTTP_PROXY = 'http://127.0.0.1:3128'
process.env.http_proxy = 'http://127.0.0.1:3128'
process.env.https_proxy = 'http://127.0.0.1:3128'
process.env.HTTPS_PROXY = 'http://127.0.0.1:3128'
process.env.PROXY = 'http://127.0.0.1:3128'
process.env.proxy = 'http://127.0.0.1:3128'


// Imports the Google Cloud client library
const language = require('@google-cloud/language');

// Instantiates a client
const client = new language.LanguageServiceClient({
    projectId:'CNL-Showcase',
    keyFilename: 'path/to/file/creds.json'
});



const document = {
    content: request,
    type: 'PLAIN_TEXT',
    language: 'DE',
    encodingType: 'UTF-8'
};
console.log('sending to Google Api');

client
    .analyzeEntities({ document: document })
    .then((results: any) => {
         ...
    }).catch((err: any) => {
        console.error('ERROR:', err);
        res.send(err);
    });

注意：我的creds文件的路径是故意更改的，如上所述，如果我不支持代理，它就可以正常工作

控制台输出如下所示：

我无法确定问题的原因，因为握手似乎很有效

经过广泛的搜索，我找到了一个解决方案：
安装代理服务器，通过代理服务器路由本地计算机上库的请求

对于Windows，我发现了两个应用程序：

我希望这能帮助那些试图在代理网络上运行PubSub的人。

这里也一样。你找到解决办法了吗？不幸的是没有。我还没有找到任何解决方案，但在我发布问题一周左右后，我就不再寻找解决方案了。
