Json decoder error

[iwatobipen]

Dear Developper,

Thanks for developping such as useful package for cheminformatics!
I found issue of maize-contrib with vina docking.
When I run the docking with vina from maize-contrib I got follwoing error.

File "/Users/pen/opt/anaconda3/envs/maize/lib/python3.10/json/decoder.py", line 337, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/Users/kzfm/opt/anaconda3/envs/maize/lib/python3.10/json/decoder.py", line 355, in raw_decode
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

The error occured when I use meeko ver 0.5. And when I used meeko 0.4.x it worked well.
yml file requred meeko >= 0.5
So I think this is an issue of the maize-contrib.
Thanks,
