When I run the system tests against stage, I get an SSL error:

I don't remember the last time I ran the system tests. I'm guessing something changed. Maybe the Python version?

I downgraded the container to Python 3.9.10 and the problems go away. Then I read the failing test code.

What's going on is that requests uses httplib and when it's writing to the socket and hits an error (the HTTP server severs the connection because the body was too large), it doesn't read the server response and instead raises an error. Previously, the error is ultimately a requests.exception.ConnectionError. Now it's a requests.exception.SSLError.

So I updated the code accordingly. Everything is fine with stage and the extract_payload changes and the systemtest failures are from updating Python from 3.9 to 3.10.

willkg merged PR #805: "bug 1757815: fix systemtest SSLError issue" in 317240e.

This is fixed now.
