SteemMakers content not loading

I am very fond of the idea of SteemMakers by Hive account@jefpatat and keep a close eye on their discord channel and website. At the moment the team is small it seems but they make steady progress. Today I was looking at the site and somehow no contents loads. I opened the console and there seems to be an unhandled error causing this.

Error: This is how the site now looks for me. I also recorded the error in the recording.

Correct behavior would be to load all content. I can't really show how that should look. This is a recording from a previous bug report where the content loads:
