大家好，我正在努力弄清楚为什么我一直得到MultipleValidationErrors缺少参数。
希望有人能解决这个问题，今天我都快疯了。
错误:

SQS发送函数:
AwsSqsService.send('Request Password Reset', 'email', {
'emailTo': {
DataType: 'String',
StringValue: email
},
'emailFrom': {
DataType: 'String',

SQS代码:

let queueToUse = ''

λ:
let aws = require("aws-sdk");
let ses = new aws.SES({
region: 'eu-west-2',
secretAccessKey: '########################',

});
exports.handler = async function (event) {
const params = {
Destination: {
ToAddresses: [event["emailTo"]],
},

Lambda接收的event输入是一个SQS记录数组。您需要迭代记录并JSON.parse字符串化的主体以提取您的输入。
您没有正确地从Lambdaevent提取输入数据。event["emailBody"](和其他类似的)的值是undefined，这反过来导致sendEmail调用验证失败。
