AWS Transfer Family client returns an error with no function list_profiles in Lambda but code runs fine locally

When trying to grab the profiles from the AWS Transfer family client, it returns an error saying 'Transfer' object has no attribute 'list_profiles'. However, the same code works fine when I run it locally. It's only in AWS Lambda does it fail. I thought it might've been a permissions issue but the role has full access to Transfer Family. It also has no issues running other functions like describe_server or list_tags_for_resource so it's not like the client is somehow missing.

client = boto3.client(service_name = 'transfer', region_name = region)
response = client.list_profiles()

By the way, I tested it with other profile functions like describe_profile and the same issue with the attribute not existing happens. Here's the documentation I was following: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/transfer.html#Transfer.Client.describe_profile
