Why does fetch_profile_card return nothing when using Dota2 Python API?

I'm using the dota2 python library to gather data from the Dota2 game client. Using the initial example I use the provided function:

@dota.on('ready')
def fetch_profile_card():
    jobid = dota.request_profile_card(70388657)
    profile_card = dota.wait_msg(jobid, timeout=10)

    if profile_card:
        print (str(profile_card) )  

As I understand gevent - the way to invoke the above function is like so:

dota.on('ready',fetch_profile_card)

When I do this nothing happens. No error but the response is None.

Some additional context:

I have logging at DEBUG

logging.basicConfig(format='[%(asctime)s] %(levelname)s %(name)s: %(message)s', level=logging.DEBUG)

When I log in I do see some output But when I run dota.on('ready',fetch_profile_card) I get nothing
