This is the sendmail.js file where i got error. here I am using amazon ses for sending mail.

AWS.config.update({ region: process.env.AWS_REGION });

// var mail = '';

function sendMail(Email) {

    var result;
    // Create sendEmail params 
    var params = {
        Destination: { /* required */
            CcAddresses: [
                Email,
                /* more items */
            ],
            ToAddresses: [
                Email,
                /* more items */
            ]
        },
        Message: { /* required */
            Body: { /* required */
                Html: {
                    Charset: "UTF-8",
                    Data: "HTML_FORMAT_BODY"
                },
                Text: {
                    Charset: "UTF-8",
                    Data: "TEXT_FORMAT_BODY"
                }
            },
            Subject: {
                Charset: 'UTF-8',
                Data: 'Test email'
            }
        },
        Source: '[email protected]', /* required */
        ReplyToAddresses: [
            '[email protected]',
            /* more items */
        ],
    };

    // Create the promise and SES service object
    var sendPromise = new AWS.SES({ apiVersion: '2010-12-01' }).sendEmail(params).promise();

    // Handle promise's fulfilled/rejected states
    sendPromise.then(
        function (data) {
            result = 'Success';
        }).catch(
            function (err) {
                result = 'Failed';
            });
}

export default sendMail;

dynamicid.js

This is the dynamic id .js file where i wrote my endpoint code

import { getDataFromSheets } from '../../../libs/sheets';
import sendmail from '../../../libs/ses/sendmail';

export default function handler(req, res) {
  var data;
  getDataFromSheets()
    .then(sheet => {
      data = sheet.length
      for (var i = 1; i < data; i  ) {
        sendmail(sheet[i].Email)
      }
    })
    .catch(err => console.log(err))

}

CodePudding user response：

Each endpoint function must end the request-response cycle by sending a response ( res.send(), res.json(), res.end(), etc). So the solution would be:

export default function handler(req, res) {
  var data;
  getDataFromSheets()
    .then(sheet => {
      data = sheet.length
      for (var i = 1; i < data; i  ) {
        sendmail(sheet[i].Email)
      }
      res.json({status: 'success', message: 'email has been sent'})
    })
    .catch(err => {
      console.log(err)
      res.json({status: 'fail', error: err})
    })
}
