Hi @shaun-nx thanks for reporting!

Be sure to check out the docs and the Contributing Guidelines while you wait for a human to take a look at this 🙂

Cheers!

For environments that are not offline, but secured by a firewall, having the schema somewhere more specific than raw.githubusercontent.com would also help, as a workaround.

There also some rate limits for raw files serving, so will be nice to make schema validation in offline mode.
