🐛 [Firestore-send-email] The default replyTo field is not overridden when using GMAIL smtp

[Dan1ell]

Configuration

• Extension name: _ firestore-send-email
• Extension version: _ firebase/firestore-send-email@0.1.34
• Configuration:
  _ SMTP connection URI: smtps://xxx@gmail.com@smtp.gmail.com:465
  _ Both the default FROM and default REPLY-TO are set. Mail sending works. Reply to header gets set in received emails.

Problem

Trying to override default Reply To address but it's not working.

Steps to reproduce:

Create a firestore document for use by the extension as follows:

 export const sendEmail = functions.https.onCall((data, context) => {

  const emailAdress = data.to;
  const subject = data.subject;
  const body = data.body;
  const replyTo = data.replyTo;

  try {
    db.collection("mail")
      .add({
        to: emailAdress,
        message: {
          subject: subject,
          html: body,
          replyTo: replyTo
        },
      });
    functions.logger.info("Completed sendEmail for: " + subject);
    return null;
  } catch (error) {
    functions.logger.error("Error within sendEmail: " + error.message);
  }
});

Expected result

The email address sent along with the document appears in the Reply To header of the received email.

Actual result

There are no errors but the default email address from the extension's configuration appears in the email's reply to header instead of the replyTo email address sent along in the document.

same problem.
my replyTo field contains email address (string), but same result.

if i try to change "Default REPLY-TO address (Optional)" in extension configuration from default value to different, i have:
"There was an unknown error while processing the request."

Have you tried moving the replyTo field one level higher?
Like this:

db.collection("mail")
  .add({
    to: emailAdress,
    replyTo: replyTo
    message: {
      subject: subject,
      html: body
    },
  });

The documentation says it should be present within sender and recipient fields, not message fields.
