aws-lambda - API网关响应状态为0，集成延迟10000ms

Question

这是我从 API Gateway 自动生成的 javascript SDK 返回的错误。

{
    "data": "",
    "status": 0,
    "statusText": "",
    "headers": {

    },
    "config": {
        "method": "POST",
        "headers": {
            "Content-Type": "application/json",
            "Accept": "application/json",
            "x-amz-date": "20180127T231842Z",
            "Authorization": "AWS4-HMAC-SHA256 Credential=.....",
            "x-amz-security-token": "....."
        },
        "timeout": 0,
        "transformRequest": [null],
        "transformResponse": [null],
        "url": "https://somevalues.execute-api.us-west-2.amazonaws.com/env/some/path",
        "data": "{\"startDay\":0,\"endDay\":1}"
    }
}

我查看了我的cloudwatch日志，调用成功了。我将 API 网关绑定(bind)到 AWS lambda 作为无服务器函数设置。

我从未见过此类错误，但今天我遇到了 5 个错误。随后的调用全部成功。

编辑:这可能与 CORS 设置有关吗？ API Gateway 似乎每隔一段时间就会出现问题，并且不会发回适当的 CORS。可能是当功能很冷的时候？我不确定...

编辑 2:我刚刚验证 - 我的所有 OPTIONS 端点(即用于 CORS 的端点)不需要 auth 或 api key 。所以我认为不是这样的。

编辑 4:编辑 3 错误，我到达了错误的端点。使用curl 访问我的API OPTIONS 端点可以正常工作。

编辑5:查看cloudwatch中的API网关日志，它们看起来是这样的......此时完全迷失了。

编辑7:这是我编写的每个函数的开始方式......

module.exports.unsubscribeFromDailyEmails = function(event, context, cb) {
  logRequest(event, context);
//more logic

function logRequest(event, context) {
  console.log('event: ' + JSON.stringify(event));
  console.log('context: ' + JSON.stringify(context));
}

我想强调的是，在我所说的情况下，logRequest 函数永远不会被调用——没有日志写入到云监视中。是的，logRequest 是我在每个函数中做的第一件事。

编辑 8:我在过去一周左右没有看到这种情况发生...所以也许它是在 AWS 端并且已修复？如果我发现其他情况，我会更新。

编辑 9:我现在已经看到由于抛出异常且未处理异常而在其他一些端点上发生这种情况。但是，这与 10000 集成延迟错误不同。
