favoriteTimelineByUsername - client.v1.favoriteTimelineByUsername is not a function

[ratracegrad]

I am trying to get the likes for a username using v1 API. I have a straightforward Node.js app that creates a Twitter client and then calls a method to get users' likes.

Using: "twitter-api-v2": "^1.12.2"
API Version: v1

const getFavorites = async(username) => {
	const favoritesTimeline = await client.v1.favoriteTimelineByUsername(username);
	const fetchedTweets = favoritesTimeline.tweets;
	for (const tweet of fetchedTweets) {
		console.log(tweet)
	}
}

getFavorites('ratracegrad');

When I run this I get an error saying that this method does not exist:

        const favoritesTimeline = await client.v1.favoriteTimelineByUsername(username);
                                                  ^

TypeError: client.v1.favoriteTimelineByUsername is not a function

If I replace the method with userTimelineByUsername then it shows me tweets. But I want to be able to get the likes. Any suggestion on what I am doing wrong?
