I've been trying to get the basic example to work in Jupyterlite, just changing micropip to instead use the %pip magic:

%pip install -q pyodide-http requests

import pyodide_http
pyodide_http.patch_all()  # Patch all libraries

import requests
response = requests.get('http://raw.githubusercontent.com/statsbomb/open-data/master/data/lineups/15946.json')

The cells run without errors, but the response object has a status code of 0, and response.content is empty. Am I missing something?

The result is the same running locally using jupyter lite serve, and on GitHub Pages.
