Not able to change the image

[GoutamShanbhag]

I am trying to change the image which appears on my RSS feed banner, I used image option in the feedOptions but it is not changing
I don't know what I am missing

const feedOptions = {
title: 'ABCABC',
description: 'ABCABC',
id: 'ABCABC',
image: ${baseURL}/favicon/favicon-32x32.png,
link: baseURL,
favicon: ${baseURL}/favicon.ico,
copyright: 'Copyright 2023',
feedLinks: {
rss2: ${baseURL}/rss.xml
}
};

baseURL = HTTP://localhost:3000

Expected behavior
I want to change the image which shows up on the banner

Actual behavior
Now it shows "I" as image
