`NoneType` object has no attribute `debug`

springserve==0.8.10

I am trying to configure credentials in code instead of using link as described in the documentation, but I get an error:
'NoneType' object has no attribute 'debug'.

Python 3.11.5 (main, Sep 11 2023, 13:54:46) [GCC 11.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import springserve
problem loading link, this is ok on the install
>>> springserve.set_credentials(user='blah@blah.com', password="mypassword")
