"TypeError: __init__() got an unexpected keyword argument 'headers'" Error when importing TCMS from tcms_api

I'm running Python 3.8.3

From the following code, from tcms_api import TCMS throws an error.

    from tcms_api import TCMS

    rpc_client = TCMS()

    test_case = rpc_client.TestCase.create({
        'summary': 'My testing',
        'product': 2,
        'category': 2,
        'priority': 1,
        'is_automated': True,
        'text': 'my first test case',
        'case_status': 2,  # CONFIRMED
    })

Error:

Traceback (most recent call last):

    super().__init__(use_datetime=use_datetime,

Process finished with exit code 1

I have endlessly looked everywhere online and haven't been able to find anybody with the same issue. I am wondering if anybody has experienced this problem or knows how to solve it. Any help with this would be greatly appreciated.

SOLUTION: For anybody experiencing the same issue, I have solved it by downgrading to Python 3.6. The API does not seem to be compatible with 3.8. Hope this helped someone.
