  const fetch = require('node-fetch')
  const {validationResult} = require('express-validator')
  const jwt = require('jsonwebtoken')
  //Esto es para obtener el error de la  base de datos, se puede personalizar para hacerlo amigable.
  const { errorHandler} =require('../helpers/dbErrorHandling')
  //el siguiente const se usará para enviar correos
  const sgMail = require('@sendgrid/mail')
  
  const pool = require('../database/connection')
  
  
  
  
  
  
  
  
  exports.AuthController = (req, res) =&gt; { 
      const email = (req.params.email);
      let sql = `select User_email from user where User_email = ${email}`;
      const mail = poo.query(sql);
  
      if(email.length = 0) {
          return res.json({
              code: 404,
              message: &quot;Equipo no encontrado&quot;,
              data: [],
          })
