[joeyfigaro]

Describe the problem

I can't get any modpacks to work properly in a 1.20.1 server. I've tried dozens.

I've tried two file IDs: one for the server modpack and one for (what I assume is) the client modpack. If I use the server modpack's file id, I get an error saying there's no manifest.json and to make sure I'm using a client modpack. If I use the client modpack, I get the error pasted above. I've also tried specifying the java version as part of the image to no avail.

I see issues with mod duplication–is that the core issue here?

edit: forgot to remove CF api key. Regenerated and redacted here.

Since there are several in the examples directory that work, there might be something that got out of sync in your data directory. You could try wiping the directory. Also, re-pull the image to make sure you have the latest.
