Producing binaries that embed Python applications that import jsonschema is challenging because pkgutil.get_data relies on __file__ which may not be always defined, e.g. see these issues in PyOxidizer.

https://github.com/Julian/jsonschema/blob/272b4f24437d9cba1127058dc3479f9bc6d8c4b9/jsonschema/_utils.py#L49-L55

I was wondering if this project would be interested in having a fallback implemented that is capable to load the schema files using importlib.resources instead, which was added in Python 3.7. See https://stackoverflow.com/a/20885799 for more details. The creator of PyOxidizer, Gregory Szorc, shares some good details on loading resource files using PyOxidizer here.
