Unknown state ID errors in CI #1261
Description
Recently some CI runs, such as this one, have failed with an argo_client.interaction.ArgoException: Unknown state ID error message. So far, I've only seen these on macOS, but it's possible that they could occur on other platforms, too.
In case the log above gets garbage collected, the relevant snippet of error message is as follows:
