我有一个API网关资源,运行一个lambda函数。我正在使用来自我的API网关的AWS生成的SDK调用API网关资源。
这是从我的客户端中似乎相关的堆栈跟踪部分:
这是从我的客户端中似乎相关的堆栈跟踪部分:
Caused by: com.amazonaws.mobileconnectors.apigateway.ApiClientException: {"message": "Internal server error"} (Service: DevnetcountableClient; Status Code: 500; Error Code: null; Request ID: 348e8f98-6f55-11e6-97f6-098c2caf220f)
at com.amazonaws.mobileconnectors.apigateway.ApiClientHandler.handleResponse(ApiClientHandler.java:255) at com.amazonaws.mobileconnectors.apigateway.ApiClientHandler.invoke(ApiClientHandler.java:88)
at java.lang.reflect.Proxy.invoke(Proxy.java:393)
at $Proxy1.accountCreatePost(Unknown Source)
现在看到AWS控制台,在我的Api Gateway仪表板中,我看到请求进来并导致“AWS/ApiGateway 5XXError”。但是没有日志(我找不到)。我的lambda函数似乎没有被调用,并且没有显示任何lambda日志。
现在我的lambda函数看起来像这样:
module.exports.createAccount = function(event, context, cb) {
console.log('createAccount');
console.log(event);
console.log(context);
console.log(cb);
cb(null, {status: 'SUCCESS', message: 'I ran!'});
};
我该怎么调试这个问题?
编辑:好的,下面是将所有内容组合在一起的CloudFormation脚本。

编辑2:当我在AWS控制台中使用API Gateway的测试功能测试端点时,一切都很顺利:/
编辑3:再次更新了CloudFormation脚本-仍然无法正常工作。
