У меня есть динамический c шаблон в SendGrid, использующий Postman с запросом POST к https://api.sendgrid.com/v3/mail/send
со следующим json:
{
"personalizations": [{
"to": [{
"email": "dariusgoore@gmail.com",
"name": "test"
}],
"dynamic_template_data":{
"name":"John",
"text": "Someone just added a new post!",
}
}],
"from": {
"email": "team@writerboards.com",
"name": "test"
},
"reply_to": {
"email": "dariusgoore@gmail.com",
"name": "test"
},
"template_id": "d-c8f201dd360d40bc877da13a1a0b36b1"
}
работает для отправки электронного письма с использованием шаблона.
Однако я не могу отправить аналогичный запрос от Express.
Вот мой маршрут, который вызывает SendGrid (конец точка отвечает на задание cron):
const express = require('express');
const User = require('../models/User');
const Act = require('../models/Act');
const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
let router = express.Router();
router.get('/', async (req, res) => {
// getdate 14 days ago
var ago_date = new Date();
ago_date.setDate(ago_date.getDate()-0)
// loop through users
console.log('crons: getting users');
const users = await User.query();
console.log('crons: number of users: ', users.length);
for (const user of users) {
console.log(user.username)
const lastAct = await Act
.query()
.where('users_id', user.id)
.orderBy('created_at', 'desc')
.limit(1);
const msg = {
to: 'dariusgoore@gmail.com',
from: 'team@writerboards.com',
templateId: 'd-c8f201dd360d40bc877da13a1a0b36b1',
dynamic_template_data: {
subject: 'Testing Templates',
name: 'Some One',
text: 'Denver',
},
};
console.log('this is the msg 2b sent: ', msg)
const {
classes: {
Mail,
},
} = require('@sendgrid/helpers');
const mail = Mail.create(msg);
const body = mail.toJSON();
console.log('this is the body: ', body);
await sgMail.send(msg);
res.json({
success: true, message: 'ok'
}); // respond back to request
// };
};
res.json({
success: true, message: 'ok'
});
});
вот трассировка ошибок, показывающая ошибку:
