I'm seeing problems too.  The API is returning (for me) this error:

{
    data: {
        feedback: null
    },
    errors: [
        {
            "code": "DOWNSTREAM_SERVICE_ERROR",
            "serviceName": "python"
        }
    ]
}

I would imagine that the developers of KA are working on the back-end processing & API stuff.

I just realized that this might have something to do with Vexcess being banned - I do remember his comment being one of the top comments on CircLand, and a similar thing happened when ski was banned, so this is probably the case.

Hi Electric Dolphin,

Thanks for reporting this! I was able to reproduce this issue on my end and have filed a bug report with the team for further investigation.

There's not a workaround for the issue at the moment, but our development team is still working on the discussions features and should be taking a look at the issue soon.

I believe this issue should be fixed now, but please let me know if you're still running into any issues!
