AWS启用我的API触发lambda的CORS

我设法创建了一个做两件事的AWS lambda：在Dynamo DB上写入并将SMS发送到手机号码。然后，我通过API Gateway Post Call调用此lambda，它在AWS控制台的测试部分中效果很好，但它在Postman和我自己的网站上都会出现错误。以在Lambda上处理CORS，并通过控制台在我的API上部署 +已启用的CORS并部署了COR

我插入了一个回调， “消息”：“内部服务器错误” }

通过我的网站（jQuery ajax post呼叫）错误：lambda呼叫失败：{“ readystate”：4，“ ponsponseText”：“ {” severse'：“ nestern Server error”}“}”，“ Responsejson”：“ wendmentjson”：{“ message”：{“ message”：'： “内部服务器错误”}，“状态”：500，“ statustext”：“错误”}

这是我的lambda代码

const AWS = require('aws-sdk');
const dynamodb = new AWS.DynamoDB();
const SNS = new AWS.SNS();
const tableName = "#####";  
let params = {
                PhoneNumber: 'mynumber####',
                Message: 'Someone wrote!'
             };

exports.handler = (event, context, callback) => {

    dynamodb.putItem({
        "TableName": tableName,
        "Item" : {
            "Id": {
                N: event.Id
            },
            "Type": {
                S: event.Type
            }
        }
    }, function(err, data) {
        if (err) {
            console.log('Error putting item into dynamodb failed: '+err);
        }
        else {
            console.log('Success in writing, now starting to send SMS');
            return new Promise((resolve, reject) => {
                SNS.publish(params, function(err, data) {
                    if(err) {
                        console.log("Error in sending sms alarm");
                        reject(err);
                    }
                    else {
                        console.log("SMS alarm sent!");
                        resolve(data);
                    }
                })
            })
        }
    });
    callback(null, {
        statusCode: 200,
        headers: {
            "Access-Control-Allow-Headers" : "Content-Type",
            "Access-Control-Allow-Origin": "*",
            "Access-Control-Allow-Methods": "OPTIONS,POST,GET"
        },
        body: JSON.stringify('Hello from Lambda!'),
    });
};

我在做什么错？我认为Lambda上的权限不是这里的问题，因为在游戏机上对其进行测试既可以在Dynamo上都将SMS发送到我的手机上。

如果我在API端点上单击此处，我会得到相同的错误{“消息”：“内部服务器错误”}

I managed to create an AWS Lambda that does two things: writes on a dynamo DB and sends an SMS to a mobile number. Then I call this Lambda through a API Gateway POST call, and it works great from the Test section on AWS console but it gives error both on Postman and my own website. I inserted a callback to handle CORS on Lambda and deployed + enabled CORS on my API via console and deployed it but still get errors:

Errors via postman call: {
"message": "Internal server error"
}

Errors via my website (jquery ajax POST call): Lambda calling failed: {"readyState":4,"responseText":"{"message": "Internal server error"}","responseJSON":{"message":"Internal server error"},"status":500,"statusText":"error"}

This is my lambda code

const AWS = require('aws-sdk');
const dynamodb = new AWS.DynamoDB();
const SNS = new AWS.SNS();
const tableName = "#####";  
let params = {
                PhoneNumber: 'mynumber####',
                Message: 'Someone wrote!'
             };

exports.handler = (event, context, callback) => {

    dynamodb.putItem({
        "TableName": tableName,
        "Item" : {
            "Id": {
                N: event.Id
            },
            "Type": {
                S: event.Type
            }
        }
    }, function(err, data) {
        if (err) {
            console.log('Error putting item into dynamodb failed: '+err);
        }
        else {
            console.log('Success in writing, now starting to send SMS');
            return new Promise((resolve, reject) => {
                SNS.publish(params, function(err, data) {
                    if(err) {
                        console.log("Error in sending sms alarm");
                        reject(err);
                    }
                    else {
                        console.log("SMS alarm sent!");
                        resolve(data);
                    }
                })
            })
        }
    });
    callback(null, {
        statusCode: 200,
        headers: {
            "Access-Control-Allow-Headers" : "Content-Type",
            "Access-Control-Allow-Origin": "*",
            "Access-Control-Allow-Methods": "OPTIONS,POST,GET"
        },
        body: JSON.stringify('Hello from Lambda!'),
    });
};

What am I doing wrong? I don't think permissions on lambda are the problem here, since testing it on console works both on writing on dynamo both sending the sms to my cellphone.

If I click from here on API Endpoint I get the same error {"message": "Internal server error"}
