getting Error: {'API client': JSONDecodeError('Expecting value: line 1 column 1 (char 0)')} on opnsense 23.7.7

[matso42]

I'm trying to use this to manage host overrides in OPNsense from Windows (Win10 LTSC 22) with python 3.12 (64 bit)

Using a known working key/secret I get {'API client': JSONDecodeError('Expecting value: line 1 column 1 (char 0)')} when running opn-cli unbound host create --hostname '*' --domain example.com --rr A --server 192.168.1.254
