Payload Too Large is because of this change.
I don’t know about the project mentioned above, but here is the status for bennylope’s project. Maybe the same fix is needed on other wrappers as well.
GitHub - pydiscourse/pydiscourse: A Python library for the Discourse API issue #38 fixes the problem, but the fixed version has not yet been pushed to pypi- pydiscourse.exceptions.DiscourseClientError: Payload Too Large · Issue #38 · pydiscourse/pydiscourse · GitHub. Waiting for github @bennylope to do it. So you can wait for pypi to be updated, or git pull master.
