AttributeError: 'NoneType' object has no attribute 'functions'

My code was working with 0.1.21, after upgrading to 0.1.22 I am getting this error after instantiating Synthetix this way:

    snx = Synthetix(
        network_id=42161,  
        provider_rpc="https://arbitrum-one-rpc.publicnode.com"  
    )

Not sure what's happening, it seems to be breaking changes in the new release.

Here the log:
