pipe-mail intialization crashes

[schliemannosaurusrex]

Hi there,

I've got following issue when trying to send a mail via pipe-mail

script

#!/bin/bash

function sendMail() {
export PIPEMAIL_SMTP_HOST=smtp.gmail.com
export PIPEMAIL_SMTP_PORT=587
export PIPEMAIL_SMTP_USER=
export PIPEMAIL_SMTP_PASSWORD=

toAddress=$1
subject=$2
export PIPEMAIL_FROM=<from_address>
message=$3

echo "To: "$toAddress
echo "Subject: "$subject
echo "Message: "$message
tempFile=$(mktemp)
echo "${message}" > $tempFile
$(/usr/local/bin/pipe-mail -s "${subject}" "{$toAddress}" < $tempFile)
rm $tmpFile

}
sendMail <to_address> "Testmail" "This is a test!"

the are of course filled correctly ;)

OUTPUT

To: <to_address>
Subject: Testmail
Message: This is a test!
/usr/local/lib/node_modules/pipe-mail/lib/createTransporter.js:2
const nodemailerOptions.host = options.host;
^^^^^^^^^^^^^^^^^

Do you have any clue? I installed via npm and I'm using node v10.24.0 -> maybe it's incompatible!?

Thanks in advance for any help.

Best regards
