What's Wrong?

I followed each and every instruction mentioned there from using command 'crossplane xpkg init function-xbuckets https://github.com/crossplane/function-template-python -d function-xbuckets' to create a folder till 'hatch run development' but the example never works.

Errors I get:
function-xbuckets.venv-default\Lib\site-packages\google\protobuf\runtime_version.py:98: UserWarning: Protobuf gencode version 5.29.0 is exactly one major version older than the runtime version 6.31.1 at crossplane/function/proto/v1/run_function.proto. Please update the gencode to avoid compatibility violations in the next runtime release.
warnings.warn(

I request either update the example or fix the docs.

Also if I am missing something then please let me know. 😁

Update: I had to add some more logs and traceback to understand the issue.
This happens because:

• asyncio.loop.add_signal_handler() is not implemented on Windows
• The Crossplane Python SDK’s runtime.serve() uses add_signal_handler() to handle signals (e.g., Ctrl+C), but this isn't supported on Windows' asyncio event loop.

It would be good if these things are mentioned in the doc. I will be running it in wsl.
