Describe the bug

A team member recently changed the JWT timeout to 5 minutes, which exposed an issue with Python request proxies. We got the JWT when opening the code editor. When the editor was open for more than 5 minutes, the API call would fail.

Expected behavior

Making an API call after the editor is open for 5 minutes doesn't fail. JavaScript should be fine.

Reproduction

Steps to reproduce the behavior:

1. Create a Python code cell
2. Make an API request, should be fine (keep code editor open
3. Wait 10 minutes (or at least 5)
4. Make the API request again
