the converter doesn't work with the gsheet example

[djarecka]

I've tried to use the sheets2linkml with the example of gsheet you provide, but I get the error:

(models_linkml) MacBook-Pro-2:linkml dorota$ sheets2linkml --gsheet-id 1wVoaiFg47aT9YWNeRfTZ8tYHN8s8PAuDx5i2HUcDpvQ personinfo types prefixes -o personinfo_gsh.yaml

The above exception was the direct cause of the following exception:

I've installed your package from pip, v0.1.21, python3.9, OSX.
