AWS（SES + API 网关）+ HTML 表单失败。错误为：InvalidParameterValue：缺少最终的“@domain”

我正在尝试在我的网站上设置联系表单，我觉得已经很接近了，但源地址值出现了一些问题。我以 URL 编码而不是多部分的形式传递数据，因为我只需要一些文本。

联系表：

<form id='contact-form'>
  <label for='replyTo'>Email</label>
  <input name='replyTo' id='replyTo' type='email' autocomplete='email' required>
  <label for='subject'>Subject</label>
  <input name='subject' id='subject' required>
  <label for='message'>Message</label>
  <textarea name='message' id='message' autocapitalize='sentences' maxlength='3000' minlength='10' placeholder='Comment text' rows='3' spellcheck='true' required></textarea>
  <button id='submit-btn' type='button'>Send</button>
</form>

Javascript 处理程序：

const submitBtn = document.getElementById('submit-btn'),
      htmlForm = document.getElementById('contact-form'), //contact form
      endpoint = "https://xxxxxxxxxx.execute-api.us-west-2.amazonaws.com/Email";

submitBtn.addEventListener('click', () => {
  const formData = new FormData(htmlForm),
  urlEncodedData = new URLSearchParams();
  for (const pair of formData.entries()) {
    urlEncodedData.append(pair[0], pair[1]);
  }
  htmlForm.requestSubmit();
  fetch(endpoint, {
    method: "post",
    body: urlEncodedData,
    headers: {
      "Content-Type": "application/x-www-form-urlencoded"
    }
  }).then(response => {
    if (response.ok) {
      resetForm();
    } else {
      throw new Error('HTTP error. Status: ${response.status}');
    }
  });
});

htmlForm.addEventListener('submit', (event) => {
  event.preventDefault(); // prevents submitting to self (page)
});

Lambda 函数：

const AWS = require('aws-sdk'),
      ses = new AWS.SES(),
      querystring = require('querystring');

exports.handler = async (event) => {
  const formData = querystring.parse(event.body),
        message = formData.message,
        replyTo = formData.replyTo,
        subject = formData.subject,
  emailParams = {
    Source: "form@<verified_domain_tld_here>",
    Destination: {
      ToAddresses: ["<my actual email address>"]
    },
    Message: {
      Subject: {
        Data: `${subject}`
      },
      Body: {
        Text: {
          Data: `${message}`
        }
      }
    },
    ReplyToAddresses: [`${replyTo}`]
  };
  try {
    await ses.sendEmail(emailParams).promise();
    console.log(successMessage);
    return {
      statusCode: 200,
      body: JSON.stringify({ message: successMessage })
    };
  } catch (err) {
    console.log(err);
    return {
      statusCode: err.statusCode || 500,
      body: JSON.stringify({ message: err.message || errorMessage })
    };
  }
};

事实证明，数据是通过这种方式编码成 Base64 的：const formData = new FormData(htmlForm)这意味着我必须在服务器端对其进行解码，然后才能正确解析正文。
