Errors when following setup instructions

[jasonericson]

Hi there, I'm very green when it comes to webdev stuff (experienced in desktop game dev mostly), so I could very well be doing something wrong, but I'm trying to get the example going with the readme instructions and running into problems:

1. Following the steps exactly, I get an error when running step 6, that port 3000 is already in use. I assume this is due to a collision with the port from running the docker memgraph command; I changed the port in the .env to 3001 and that seemed to work.
2. Now I just want to check that the example is working, before I work on my own feed, which I'm guessing I do by opening http://localhost:3001/xrpc/app.bsky.feed.getFeedSkeleton?feed=at://did:plc:ewgejell4547pukut5255ibm/app.bsky.feed.generator/home-plus&limit=20 directly, but all I get is an UnsupportedAlgorithm error at that point. Any idea what might be going wrong there?
