Nodemailer在失眠中工作，但不在我的网站上

如何解决Nodemailer在失眠中工作，但不在我的网站上

当我通过Insomnia发出请求时，它会起作用并发送电子邮件（请参见图片）。
当我浏览我的网站时，它会返回状态200，但不会发送电子邮件。

禁用了我可以从Google获得的所有安全配置。
从这里https://community.nodemailer.com/using-gmail/

尝试了一切

尝试解决此问题的时间少于2小时。

const functions = require('firebase-functions');
const admin = require('firebase-admin');
const nodemailer = require('nodemailer');
const smtpTransport = require('nodemailer-smtp-transport');
//const cors = require('cors')({origin: true});
admin.initializeApp();

/*let transporter = nodemailer.createTransport({
    host: 'smtp.gmail.com',port: 465,secure: true,auth: {
        user: '[e-mail]',pass: 'xxxxx'
    }
});*/

let transporter = nodemailer.createTransport(smtpTransport({
    host: 'smtp.gmail.com',pass: 'xxxxx'
    }
}));

exports.processForm = functions.https.onRequest((req,res) => {

    const body = req.body;

    const nome = body.nome;

    const subject = `${day}/${month}/${year} - Solicitação de análise criada em Poços da Serra!`;
