Next.JS Getting a 500 Server Error When Trying to Submit my Form with Nodemailer [closed]

Question

import { type NextRequest, NextResponse } from 'next/server';
import nodemailer from 'nodemailer';
import Mail from 'nodemailer/lib/mailer';


export async function POST(request: NextRequest) {
    const { email, name, message } = await request.json();
    const EMAIL ="myMail";
    const PASSWORD="appPassword";

    const transport = nodemailer.createTransport({
      
        //setting service as 'gmail' is same as providing these setings:
        host: "smtp.mail.yahoo.com",
        port: 465,
        secure: true,
        service: 'yahoo',
        
      auth: {
        user: EMAIL,
        pass: PASSWORD,
      },
    });
  
    const mailOptions: Mail.Options = {
      from: process.env.MY_EMAIL,
      to: process.env.MY_EMAIL,
      subject: `Message from ${name} (${email})`,
      text: message,
    };
  
    const sendMailPromise = () =>
      new Promise<string>((resolve, reject) => {
        transport.sendMail(mailOptions, function (err) {
          if (!err) {
            resolve('Email sent');
          } else {
            reject(err.message);
          }
        });
      });
  
    try {
      await sendMailPromise();
      return NextResponse.json({ message: 'Email sent' });
    } catch (err) {
      return NextResponse.json({ error: err }, { status: 500 });
    }
}

I am new to Next.js and I am getting an error when I send my form, it's giving me a 500 Server error. I am trying to go through yahoo as my mail provider I have created an app password, I can't work out what is going wrong. I'm wondering is the credentials my end or am I missing something in the API? Your help would be greatly appreciated. Here a some screenshots of my code.[[[[[enter image description hereenter image description here](https://i.sstatic.net/pg1eFSfg.png)](https://i.sstatic.net/ztxRRE5n.png)](https://i.sstatic.net/4hdUOR9L.png)](https://i.sstatic.net/CbdjU9Fr.png)](https://i.sstatic.net/AdKHNV8J.png)
