i have a controller that sends email with nodemailer. my app is running o plesk. when i run it in my localhost every thing is ok. but when i run it on host with plesk i get this error : Incomplete response received from application

my function :

```
submitInvoice = async (req, res, next) => {
try {
var transporter = mailer.createTransport({
host: process.env.mailhost,
port: 587,
auth: {
user: process.env.mailuser,
pass: process.env.mailPass,
},
tls: { rejectUnauthorized: false },
});

var mailOptions = {
from: process.env.mailuser,
to: process.env.reciever,
subject: "", // Subject line
// attachments: [{ filename: "new-form.xlsx", content: data }],
html:
"<!DOCTYPE html>" +
"<html><head><title>title </title>" +
"<style>" +
"body {background-color:#ffdd00;background-repeat:no-repeat;background-position:top left;background-attachment:fixed;}" +
"h2{font-family:Arial, sans-serif;color:#000000;background-color:#ffdd00;text-align:center;}" +
"p {text-align:center;font-family:Georgia, serif;font-size:19px;font-style:normal;font-weight:bold;color:#000000}" +
"</style>" +
"</head><body><div>" +
" <h2>فایل اکسل پیوست شد</h2>" +
"</div></body></html>",
};

await transporter.sendMail(mailOptions);

return res.render("client/Counseling");
} catch (err) {
next(err);
}
};
```
the out put of nodemailer is :

Hi, did you find the solution to the problem?

I've been trying for several days to deploy an express application on plesk but without success,

I always get this error :Incomplete response received from application with http code 502

I think the error comes from the database, but as the error doesn't give me any indication it's hard to know...

Does anyone have any ideas?

Plesk uses Phusion Passenger to serve the Node app and you can check the logs at `/var/log/passenger/passenger.log`.
