Version

4.7.0

Describe the bug

I've deployed a bot, and a skill (80.skills-simple-bot-to-bot). Everything works great, until the token expires ... at which point, I'm getting an Unauthorized exception.

To Reproduce

Steps to reproduce the behavior:

1. Deploy a Python Root bot and Skill bot
2. Invoke the skill from the parent
3. Leave everything sit for ? (i believe half an hour, but still investigating)
4. Attempt to invoke the skill again
5. See unauthorized error

Expected behavior

Tokens should automatically refresh, and expired tokens should not cause Unauthorized.
