Currently jsonschema version 4.17.3 is out, and your requirement is incompatible with my company's up to date software. Also, your package deletes jsonschema version 4.17.3 and installs version 3.2.0 quietly. That led me to believe your package was compatible during development for multiple days.
I can look into running my application with jsonschema version 3.2.0 in the meantime, but I think this is something that needs to be addressed.
