trying to run sample to make a new bid

[freegrapher]

here is what error I get :
File "C:\Users\gura\AppData\Local\Programs\Python\Python37\lib\site-packages\freelancersdk\resources\users\users.py", line 14, in get_self_user_id
response = make_get_request(session, 'self')
TypeError: make_get_request() missing 1 required positional argument: 'params_data'

so ...
in users.py you have :make_get_request(session, 'self') <-two parameters passed

in definition of make_get_request you have :

def make_post_request(session, endpoint, json_data): <- three parameters required.

sorry Im just begginer so can you tell me if Im doing something wrong?
