Hey looked into this error, Porter was not processed by us yet, it does take a while for a repo to be processed initially but this link should give you the progress report + you can chat with it when its done:
It also appears that the vote buttons do nothing if one is not logged in, so I'd recommend eliding them unless logged in since it's just frustrating to wonder if some JS error ate the vote or what
I shudder to think how much you must be spending on compute asking for that /api/poll/batch once a second, each one saying it is a Miss from cloudfront. It's especially mysterious since there's nothing on the UI that the user would see about the .filesProcessed increasing that justifies DDoSing yourself like that, IMHO
