Folllowing the install instructions in README.md, I get this error.

python3 -m venv ga4gh-python-env

Per https://stackoverflow.com/questions/69426664/modulenotfounderror-no-module-named-jsonschema-compat, looks like downgrading jsonschema is the solution.

pip install -U 'jsonschema<4.0'

which then leads to another error

ImportError: cannot import name 'FileStorage'
