Unable to validate replyTo field without using the EmailAddress class

[edpei]

From the documentation examples:

//Many different ways to add recipients
message.to.push("recipient1@example.com");
message.to.push(new EmailAddress("recipient2@example.com"));
message.to.push(new EmailAddress("recipient3@example.com", { friendlyName: "Recipient #3" }));
message.to.push({ emailAddress: "recipient4@example.com" });
message.to.push({ emailAddress: "recipient5@example.com", friendlyName: "Recipient #5" });

i understand that for every email i have these many options to use, but for the given case of the replyTo field if i try to use the object definition directly:
replyTo: { emailAddress: data.replyTo.emailAddress }

it throws the following error:

2022-05-27T09:48:39.363Z	bee95426-8d19-5c27-b788-0f2c2db3636d	ERROR	Invoke Error 	{"errorType":"TypeError","errorMessage":"this.replyTo.toJSON is not a function","stack":["TypeError: this.replyTo.toJSON is not a function","    at e.exports.toJSON (/var/task/src/main/js/index.js:2:18636)","    at /var/task/src/main/js/index.js:2:3417","    at new Promise (<anonymous>)","    at Object.generateRequest (/var/task/src/main/js/index.js:2:2703)","    at /var/task/src/main/js/index.js:2:34672","    at new Promise (<anonymous>)","    at SocketLabsClient.send (/var/task/src/main/js/index.js:2:34552)","    at /var/task/src/main/js/index.js:2:473415","    at processTicksAndRejections (internal/process/task_queues.js:95:5)","    at async Runtime.e.exports.handler (/var/task/src/main/js/index.js:2:471749)"]}

I had to import the EmailAddress class to avoid the error. I believe since the documentation states that the declaration can be done differently there's something to be addressed.

Thanks

PD: i have other emails in the message other than the replyTo declared the same way and they work properly.
