Issues with Nodemailer in Node.js – Subject Showing in Message Body and Placeholder Issue

I’m facing an unexpected issue while using Nodemailer in Node.js via slack, The subject, which should be in the email subject line, is appearing in the message body. Below is a snippet of the relevant code

app.view('your_view_callback_id', async ({ ack, body, client }) => {
    console.log('View Submission Payload:', JSON.stringify(body, null));
    const subject = body.view.state.values.uik1r.sl_input.value;
    const message = body.view.state.values["35GrF"].ml_input.value;
    await sendEmail(client, subject, message)
    await ack();
    console.log('Acknowledged view submission', body);
});



async function sendEmail(subject, message){

    console.log('Subject:', subject);
    console.log('Message:', message);

   const transporter =  nodemailer.createTransport({
        host: 'smtp.gmail.com',
        port: 465,
        secure: true,
        auth: {
            user: process.env.EMAIL_USER,
            pass: process.env.EMAIL_PASSWORD,
        }
    })

    const info = await transporter.sendMail({
          from: "SlackEmail <motty6700@gmail.com>",
          to: "techsupport@fidelitypayment.com",
          subject:`This is just a test ${subject}`,
          text: message
    })
    console.log("message sent:" + info.messageId);
    console.log("Message info:", info);
    console.log("message rejected:" + info.rejected)
}

the subject will be logged under the message params
console.log(‘Message:’, message); as you can see in the logs

Message: Tech support
message sent:2ddfbd90-6f59-4cad-2263-b956ca9a4255@gmail.com "Tech support" was suppose to be under subject, the console.log(subject) doesn’t even show up in the logs.

I am also encountering an issue with the placeholder in the subject line. I tried adding some static content, The placeholder text is not displaying correctly, resulting in unexpected content such as "This is just a test [object Object].", but this does show up in the subject line

here you can see the full payload

I have been working on this for hours already, I appreciate any assistace into resolving this issue.

>Solution :

As it seems you call the given method with three parameters:

await sendEmail(client, subject, message)

but it requires only two:

async function sendEmail(subject, message){

• remove the unused parameter
• add another parameter like _client to the method
